About This Project

Interfacing of RGB with IR sensor objective is to On, Off and fading RGB led from remote place using IR Remote.

The TSOP 1738 is one type of receiver which receives IR. It consists of a PIN diode and a pre amplifier which are embedded into a single package. The output of TSOP is active low and it gives +5V in off state. When IR waves, from a source, with a centre frequency of 38 kHz incident on it, its output goes low.
