Resistor(s) (to keep from frying the LED, 220 Ohm should work for basic LEDs) Jumper wires Breadboard Arduino USB cord (to upload code) *alternatively, you can use a strand of pre-made LED string ...

In this experiment we are going to use a element called photoresistor. This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light ...

This project demonstrates a simple water detection system using an Arduino board and a water sensor. The system uses an LED to indicate whether water is detected. The LED turns ON when no water is ...

Anyone can hang a poster from the wall, but if you're willing to put a little DIY into your home decorations, this Arduino-powered LED wall-art looks amazing, and reacts to music playing in the room ...
