Tutorial: RGB led control using IR remote control!

The purpose of this sketch is to control an RGB LED to light up different colors

by pressing different buttons on an IR remote.

Connections from the Arduino to the breadboard:

• Arduino GND pin → Breadboard ground line

• Arduino 5V pin → Breadboard 5V line

Connections from the RGB LED:

• Red led pin→220-ohm resistor→ Arduino pin 3

• Negative pin→ Breadboard ground line

• Green led pin→ 220-ohm resistor → Arduino pin 5

• Blue led pin→ 220-ohm resistor → Arduino pin 6

Connections from IR receiver to the Arduino:

• IR receiver GND pin (- pin) → Breadboard ground line

• IR receiver VCC pin (+ pin) → breadboard 5v line

• IR receiver signal pin → Arduino pin 9
