A potentiometer acts as the Synchro Transmitter, generating an analog voltage representing angle. Arduino reads this analog input. The value is mapped and sent to control a servo motor, which acts ...

The potentiometer's value is read using the analogRead() function, which returns values between 0 and 1023. The map() function is used to scale the potentiometer’s value to a range that suits the LED ...

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 ...
