DIY retro look FM radio with TEA5767 module

The base for this project is the code of Rodolfo Broco Manin (RodLophus on GitHub) which contains a beautiful analog scale on 16x2 LCD. I modified his code by adding two analog meters for reading the signal strength and frequency, “stereo“ LED, and “auto /manual search“LED. Also, as a retro detail, I added four memory keys whose frequencies are predefined in the code, so the radio gets a completely antique look. Audio outputs of the TEA5767, via a stereo potentiometer, are connected to the D class power amp
