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 ...

We initiate analog pin A0 as input for the photoresistor and the default pin 13 as output for the LED. We initiate a loop. We read the value of the light sensor using analogRead that changes as we ...

Before opening the Arduino software, wire up the Arduino according to the circuits page using the 8MHz minimalist breadboard circuit but with a 10k pull-up resistor on the reset pin (physical pin 1).
