How to Produce NEC-style Remote Control Signals

Exclusively for the Elektor Uno R4

The ATmega328PB micro at the heart of the Elektor Uno R4 is equipped with a so-called Output Compare Modulator (OCM). This peripheral, together with a few more, is not available on other versions of the ATmega328 found in standard Arduinos like the Uno R3. The OCM is great for generating infrared (IR) remote control signals.
