ATtiny13 – IR receiver / NEC proto analyzer

In this example we will make a project that uses standard IR remote control from your TV, audio system or other using NEC signal format, to receive and recognize address/command with AVR ATtiny13. Thanks to Software UART we will print received NEC address/command via serial console. Project has been tested with ATtiny13a @9.6 MHz, VCC=5V … Read more

ATtiny13 – IR remote to control LEDs (NEC proto)

This project allows control turn ON/OFF LEDs with IR remote control from your TV. The big part of the code shows how to decode a command and address of NEC protocol from IR signals using a cheap IR receiver. It’s worth to note that the algorithm which is responsible for decoding IR signals is nonblocking … Read more
