What is it?

The AVR Morse decoder is a nice gadget that will decode morse from your paddle or from an audio source. It features an AVR AtMega 328P clocked at 16Mhz with a 4 line by 20 characters lcd. The board features two buttons , one button changes the frequency of the audio tone so as the decoder can sweep and sync the frequency in order to find the right sweet spot to decode the incoming morse signal. This is achieved with a digital pot connected to the phase lock loop chip. The second button offers features such as noise filter, automatic sweep, brightness control. These modes are achieved with a short and long press on the button.
