16 Channel Infra-Red remote controller is built around PIC16F73 Microcontroller from Microchip. The receiver part follows NEC Code Format. Tiny receiver provides 16 latch outputs. All outputs are TTL and can drive Relay board or solid state relay. The circuit uses TSOP1738 Infra-Red receiver module which provides high degree of noise immunity against interfering light source.
