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 ...

Project Overview This project uses two Arduino boards to control the speed of a DC fan using a potentiometer. Three LEDs indicate different speed ranges: red for slow, green for medium, and blue for ...

In this project we are going to design an 8x8 LED matrix display, for that we are going to interface an 8x8 LED matrix module with Arduino Uno. An 8x8 LED matrix contains 64 LEDs which are arranged in ...

How it Controls the Light Intensity Automatically: As per the circuit diagram, we have made a voltage divider circuit using LDR and 100k resistor. The voltage divider output is feed to the analog pin ...
