The Driver module will have four LED using which we can check which coil is being energised at any given time. The complete demonstration video can be found at the end of this tutorial.. In this ...

Potentiometer: One end is connected to 5V, the other end to ground, and the middle pin (wiper) is connected to analog pin A0 on the Arduino. Working Principle The potentiometer's value is read using ...

The Arduino knob code is used to control Arduino servo with potentiometer. The code initializes a servo motor on pin 5, reads the analog value from a potentiometer on A0, maps that value to an angle ...

This Arduino project demonstrates how to use a potentiometer as an analog input to control the brightness of an LED using PWM (Pulse Width Modulation). The analog input is read from pin A0, scaled to ...

The outputs from the potentiometers are analog, so they can have a value only between 0 and 1,023 when read by the analog pin of the Arduino. This number sends a pulse to the Arduino, which in ...

We set the potentiometer pin as 0 (A0 on the Arduino Uno board), the CONTROL variable is the voltage that is used to cotrol the led brightness of the speed of the fan. In the setup() function the ...

4. PWM Signal Generation Unit. In the final step, a PWM pulse is given to the TRIAC as per the speed requirements, which in turn varies the ON/OFF timing of the AC signal and provides a variable ...
