STM32 EXIT ▶ IR Decode : Load Control using any IR remote
ARM Tutorials 🏿 EXIT ▶ Simple IR Data Decoder
Sometime we want to turn on/off some load using a remote. Audio, TV, AC remote available in market which works on AM modulated signal. That when any key pressed, a burst of AM modulated signal send through IR transmitter. In AM modulated signal the carrier signal may be 30kHz/36kHz/38kHz/56kHz. In market may IR Decoder IC available, but in our case we use TSOP1738. The IR receiver sensor works at active low, means if any IR signal of 38K AM modulated wave found the output of the IR receiver is GND otherwise it high......
