Interfacing of RGB with IR sensor

About This Project

The objective of this project is to control an RGB LED by turning it on, off, and fading it from a remote location using an IR remote control.

The TSOP 1738 is an infrared receiver containing “a PIN diode and a pre amplifier which are embedded into a single package.” The output operates as active low, outputting +5V when idle. When exposed to IR waves at a center frequency of 38 kHz from a source, its output goes low.

Components Required

• Arduino UNO
• RGB Diffused Common Cathode
• IR receiver
• Breadboard
• Resistor 1K Ohm
