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 ...

This project demonstrates how to control the brightness of an LED using a potentiometer. The analog input from the potentiometer is mapped to control the PWM output, adjusting the LED brightness ...

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 ...

Learn how to easily adjust the contrast of a 1602 LCD display using Arduino. In this quick tutorial, I’ll show you a simple trick to control the contrast electronically, without relying solely on the ...
