Using a 220 Ohm resistor going out to ground, the common cathode RGB LED is connected to pins 2, 3 and 4 of the Arduino. This will allow turning ON and OFF each of the LEDs within the package. The ...

Electronic Circuit: photocell and LED The cmd_response sketch is very general with respect to the ANALOG IN and DIGITAL I/O of the Arduino boards. We can use it to read a wide variety of sensors from ...

In this project, we're making a cool 4×4×4 LED cube with Arduino Nano. LED cubes, also known as LED Matrix, can light up your room, study space, or Maker area giving it a awesome cool look. Moreover ...

A Basic Piano made with an Arduino Board, 6 photocells, 6 LEDs and a buzzer Two Arduino sketches are included: a basic mode, and a lesson mode where the LEDs show how to play "Twinkle, Twinkle, Little ...

The photosensor is a simple cadmium sulfide cell, which measures the intensity of light bouncing back from an object as an Arduino drives the LED through all possible colors with PWM signals.
