The LED’s brightness is controlled with analogWrite(), which varies the voltage to the LED based on the potentiometer’s value. The sensor value and corresponding LED brightness are printed to the ...

This repository contains an Arduino script that demonstrates the usage of potentiometers to control LEDs. The script reads the voltage produced by a potentiometer and lights up corresponding LEDs ...

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 ...

Here is a simple, yet useful circuit of an Arduino 4-digit 7-segment LED display unit. The module used here is a self-contained, compact common-cathode module containing four 7-segment LED numeric ...
