This project demonstrates how to use Arduino and the nRF24L01 RF module for wireless communication. Specifically, it reads the value from a potentiometer on the transmitter side and controls the ...
This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...
This project demonstrates how to control the brightness of an LED using Pulse Width Modulation (PWM) on an Arduino Uno. The LED smoothly fades in and out by changing the PWM duty cycle on digital pin ...
