The 3-band resistor color code calculator is a helpful online tool that simplifies the process of determining the resistance value of a cylindrical color band resistor. For long period, resistor values are conveyed through color-coded bands painted on the resistor, which could be challenging to read, particularly for those who are not familiar with the color-coding methods. Thankfully, the 4-band resistor color code calculator eliminates the guesswork and facilitates easy determination of resistor values. With this tool, you can enter the color bands of your resistor and get an instant calculation of its resistance value, thus taking the hassle out of resistor value calculations.
To use a 3-band resistor color code calculator, simply enter the colors of each band into the corresponding fields on the calculator from left to right.
3 Band Resistor Color Code Calculator
For example, let’s say you have a resistor with the colors Brown, Black and Red. To calculate the value of this resistor using the 3-band color code calculator, you have to enter “brown” in the 1st field, “black” in the 2nd field, “red” in the 3rd field.
Press the ‘Calculate’ button to get the values. And press the ‘Reset’ button to use it again.
If you are on the way to calculate the 3 band resistor value on paper by looking at its color coded band then you can do so by following information.
Calculating the value of a 3-band resistor :
by looking at the color bands may seem challenging at first, but it’s actually quite simple once you understand how to do it:
Step 1: Identify and Determine the color for each band on resistor
Next, you need to determine the color codes for each of the 3 bands. The color codes for the first two bands represent the resistance value of the resistor. The third band represents the multiplier or number of zeros, and the fourth band is absent here, which represents the tolerance.
Step 2: Calculate the resistance value and tolerance value
In order to calculate the resistor’s resistance value, combine the first two color bands and multiply them by the multiplier value represented by the third band. The absence of fourth band represents the tolerance value of the resistor is ± 20%, which shows the range in which the actual resistance value can vary from the exact value and intended value in %.
For example, if the bands on the body of the resistor are Red, Red and Orange.
Then from the table 1st red band means significant digit of 2, second red band means significant digit 2, third is Orange means multiplier means 10^3, and the 4th Absent means 20% tolerance.
Thus, the resistor value is 22 *10^3 and its tolerance is 20% that is 22 kΩ ± 20%
A 5-band resistor color code calculator is an online tool for getting any resistor value effortlessly. Resistor values are generally represents by color-coded bands printed on the resistor itself, which can be sometimes difficult to decode even if you have remembered the color codes chart in mind. Also, it could be wondering for those who are not familiar with the resistor color code system. By simplifying the value calculations for 5-band resistors, this calculator removes the assumption involved in resistor value calculations.
To use a 5-band resistor color code calculator, simply enter the colors of each band into the corresponding fields on the calculator from left to right.
5 Band Resistor Color Code Calculator
For example, let’s say you have a resistor with the colors Yellow, Violet, Black, Red, and Gold. To calculate the value of this resistor using the 5-band color code calculator, we would enter “Yellow” in the first field, “Violet” in the 2nd field, “Black” in the 3rd field, “Red” in 4th and “gold” in the 5th field.
And press the ‘Calculate’ button to get the values. And press the ‘Reset’ button to use it again.
In case you want to calculate the 5 band resistor value manually based on the color coded bands then you can do so by following these instructions. In brief, a resistor’s value is signified by the first three bands and a multiplier by the fourth band, and the last band denotes the tolerance value.

Step 2: Calculate the resistance value and tolerance value
In order to calculate the resistor’s resistance value, combine the first three color bands and multiply them by the multiplier value represented by the 4th band. In the fifth band, the tolerance of the resistor is shown as a percentage, showing the range between the real and expected resistance values.
For example, if the bands on the body of the resistor are Yellow, Violet, Black, Red, and Gold.
Then from the table 1st Yellow band means significant digit of 4, second Violet band means significant digit 7, third is Black significant digit of 0, fourth Red band means multiplier means 10^2, and the 5th Gold means 5% tolerance.
Thus, the resistor value is 470 *10^2 and its tolerance is 5% that is 47kΩ ±5%

In this world of Electronics, a simple blinking LED circuit is a very basic yet very useful circuit. Blinking LEDs are often used in a wide range of Electronics projects from simple toys to gadgets, generally their blinking and flashing are programmed on a micro-controller or some kind of timer IC’s.
The LED flasher can be used to create a visual state indication, provide a warning signal or simply to add some stylishness to a project. The best thing is that creating a simple blinking LED circuit is relatively easy, even for those who are new to electronics and DIY.
In this article we will be discussing the basics of LED flasher circuit diagrams, including all the required components, the circuit schematic and programming if any. We will also provide step by step instruction on how to create your own Blinking LED circuit along with a few useful tips and tricks to help you get the most out of your project. Whether you are an occasional electronics enthusiast or just starting in this field, this article will provide you all the information you need to create your own LED flasher circuit and take your projects to the next level.
Blinking LED circuit with 555 Timer and only 5 components
The above image shows two red and blue indicators in and as a 555 timer blinking led circuit. This is a very simple blinking LED circuit consisting of only 5 components (except LEDs and battery). Strobe effect can be replicated with this circuit as it alternates red/blue color kinda cool though.
Its simplified connection is shown in the circuit diagram in two illustrations. You can solder it on a small compact PCB and make it portable/ versatile. Always check the polarity of the light emitting diode if anode and cathode are connected properly (incorrect polarity of LEDs is one of the most common errors).
The above circuit design implemented the design of the blinking LED with the help of timer IC 555. Out of three operation modes viz, astable mode, monostable mode, bistable mode. Here we have used the 555 timer IC in an Astable configuration.
Astable mode of operation gives two digital levels at the output, that is the output voltage will swing from high and low and low to high at regular intervals determined by RC network. This character of the astable output is used as a clock or square wave generator in various electrical circuits.
The Blinking LED circuit uses a pin number ‘3’ of 555 timer IC in astable mode, and will turn LED ON and OFF.
The duration of ON/ OFF is the duty cycle of the output square wave generated which can be changed by changing the value of the tank circuit. Also IC555 works with a wide range of voltage supply from 5V to 18V up to 200mA of load current.
All the All the circuit below uses a general purpose transistor so you can use any general purpose transistor available in your electronics project kits, you can use general transistors like BC 547 or 2N3904, BC 557, 2N2222, 2N2907 BC548,BC547. Please note that you can not substitute an NPN transistor with a PNP.
Simple One Transistor 2N3904/ BC547 LED flasher circuit
This circuit only uses the transistor’s Collector-Emitter terminal, keeping the Base terminal open. That circuit looks to be technically incorrect, however the above circuit diagram shows that even with just one transistor as the main component, you can create a working single LED flasher circuit. The circuit utilizes the negative resistance area in transistors to produce the blinking effect.
It is possible to change the flashing rate by changing either R11 or C4 or both together, but supply voltage must not be less than 9V otherwise the circuit does not work.
Even when the resistor R10 is short circuit it will work fine. The transistor in the 12V BC547 LED flasher circuit can be replaced with any general purpose NPN transistor.
Low Voltage Simple 1.5V/ 3V Single LED Flasher circuit
This circuit is very efficient and works only on as low as 1.5volts of supply, as this consumes current in the range of mAmps it lasts for very long without need to change the battery. You can power this circuit even with 3 volts and it would work fine.
3.7V/ 5V Blinking LED circuit using transistor
This is the tested and 100% working circuit of 3v LED flasher circuit, it utilizes a cross coupled transistor switching circuit as an astable multi-vibrator, but with lesser components than that of above which works on lower voltages like 3 volts and 5 volts.
The circuit shown above is the same as an Astable multivibrator design which is previously discussed above, using two transistors but with lesser components.
Blinking LED circuit using transistor in Astable Multivibrator mode
This circuit is made possible using the regenerative switching circuit. The circuit shown below is called an Astable Multivibrator design using two transistors. Astable Multi-vibrator are the most commonly used type of relaxation oscillator due to not only they are simple, reliable but also very simple to build. Also produces a constant square wave output signal which is used here in a bc547 led flasher circuit.
The video below is for reference only, flasher circuit is modified for only two resistors, it is recommended to connect all the required components if you are using this for high school projects.
The Astable Multivibrator is another type of cross-coupled transistor switching circuit that doesn’t have any stable output states, meaning its output changes from digital one to zero and vice versa. This circuit consists of two switching transistors, a cross-coupled feedback network, and two time delay capacitors which creates oscillation without the need of any external triggering circuit to produce square signals.
Here’s in short what happens in this circuit: The Capacitors C5 and C6 charge and discharge alternately through the resistors, that turns transistors off and on (cutoff region and saturation region). And thus the square waveform is created which in turns creates a flickering effect in LEDs. This can be better understand by using the below illustrations:
One can change the flickering speed of LED by changing the value of RC by using the below given formula as:
The Frequency of oscillation= Frequency of blinking= f
In the diagram below we have used D12 as an output control pin.1
The LEDs have one long leg (say, anode or positive leg). GND should be connected to the shorter leg of the LED (the negative leg, called the cathode) with the resistor 330Ω in series. And provide a power supply of 5V or whatever is available to you.
After you have built the circuit, open the Arduino Software (IDE). Connect the Arduino board to your computer and enter the following code into the IDE and dump the code to it.
Code for Blinking LED circuit:
const int LED_OUTPUT_PIN = 15;
void setup()
{
// set Pin 3 to output
pinMode(LED_OUTPUT_PIN, OUTPUT);
}
void loop() {
digitalWrite(LED_OUTPUT_PIN, HIGH); // turn LED on (output 5V)
delay(1000); // wait one second
digitalWrite(LED_OUTPUT_PIN, LOW); // turn LED off (output 0V)
delay(1000); // wait another second
}
Or
void setup()
{
// set Pin 3 to output
pinMode(15, OUTPUT);
}
void loop() {
digitalWrite(LED_OUTPUT_PIN, HIGH); // turn LED on (output 5V)
delay(1000); // wait one second
digitalWrite(LED_OUTPUT_PIN, LOW); // turn LED off (output 0V)
delay(1000); // wait another second
}

All of the above circuits are well tested for blinking LED circuits for their output as an LED indications in a blinking pattern. Try all these circuits as it requires minimal components and costs are too affordable. Due to their simple design and basic mechanics involved, it can be experimented by individuals of all skill levels.

An 18650 battery charger circuit is specifically used to safely charge 3.7 volt lithium ion batteries. 18650 batteries are lithium-ion cells that are commonly used in several electronic devices such as laptops, bluetooth speakers, portable consumer electronics and power banks. They are called 18650 batteries because they are cylindrical, 18mm in diameter and 65mm in length.
In this piece, we will discuss common 18650 battery charger circuits and popular charge controller modules. Also, it will be helpful for DIY lithium battery charger circuits.
There are different ways to design an 18650 battery charger circuit, all of them have common basic building blocks. This circuit consists of a charging controller, a power supply, and a charging port:
The main block from above is the charge controller. The charging controller regulates the charging process to ensure that the battery is charged safely and efficiently. The charge controller sets and monitors the battery’s voltage and charge current to determine according to specific needs of a particular lithium battery. It also prevents the battery from being overcharged and deep discharge. This helps increase the life of a lithium battery and thus the device.
The power supply could be any AC adapter, a USB port, or a solar panel. The power supply provides stable DC voltage that directly can’t be used to charge li-ion batteries, thus a charge controller is used. The charging port is usually a female DC jack or a micro USB port. The charging port is an input to the charging controller, which monitors the battery and controls the charging process.
18650 battery charger circuit using TP4056 charge controller IC:
The TP4056 is a popular and most widely used battery charging controller IC. It is a simple and cost-effective IC that is designed for low-power portable electronic devices such as power banks. One of the main advantages of the TP4056 IC is its low cost and simplicity. It has a simple circuit and does not require any additional components to function. It is also widely available and can be easily purchased from online retailers or electronics suppliers.
The TP4056 IC has a built-in charge controller and voltage regulator that is capable of charging lithium-ion or lithium-polymer batteries. It supports USB and AC/DC power sources, and has several safety features to protect the battery and the charger from being damaged.
You could implement an 18650 battery charger circuit using TP4056 in two ways, one directly with the TP4056 module available in the market and other with the TP4056 charger IC. Both are discussed and explained in detail below:
Below is the simple circuit diagram for the 18650 battery charger schematic according to the datasheet of Tp4056 with temperature sense disabled.
Only Red LED glows when the battery is charging and only Green LED glows when the battery is fully charged. These indicators are connected to pin number 7 and pin number 6 respectively.
So here’s the diagram: How to wire a TP4056?
Components required:
IC TP4056, 2x LED indicator, 2x Cap= 10uF, Rprog= 1.2KΩ, 2x Resistor= 1KΩ, Rs= 0.4Ω, 3.7V Lithium cell, micro USB/ USB c female connector, pcb.
Note:
This circuit can be used only for charging purposes. Rprog is chosen to be 1.2KΩ for 1000mA of output current, this can be changed by setting different values of Rprog. If you have two 18650 lithium batteries, then by connecting them in parallel, each battery will charge at 500mA of current. If you connect three then it will charge them at 1000/3 mA each, thus it will take longer to fully charge each battery. To charge 18650 battery with 2000mA current you need to use module with IC TP5100 check here TP5100 circuit and datasheet.
The charging current (IBAT) of the li ion cell can be set manually by choosing the value of Rprog. In all modes during charging, the voltage on pin 2 can be used to measure the charge current as follows:
The Rprog(KΩ) vs Ibat(mA) can be determined using following table :
Tp4056 module: 18650 Li-ion 3.7 v battery charger circuit
Overall, the TP4056 is a good option for charging single-cell lithium-ion or lithium-polymer batteries in low-power applications. It is simple, cost-effective, and widely available, which makes it a popular choice among designers and manufacturers.
