The duty cycle of PWM (and therefore LED brightness) is calculated by scaling a 0 to 3.3 V input voltage, set by a potentiometer connected to an analog input pin. The blink interval is fixed and has ...

The provided C++ code utilizes the Arduino framework to control three LEDs based on the input from a potentiometer. Here is a breakdown of the main components and functionalities: Declarations: ...

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 ...
