If you’re looking for a simple way to make an RF transmitter, check out [Tomasz]’s Morse code transmitter. His design uses nothing more than a microcontroller and a 16MHz crystal to tra… ...

In these situations, a simple decoder like [Rostislav]’s is completely sufficient. We wrote about a couple of Morse code algorithms back in 2014, the MorseDetector and the Magic Morse algorithm.
