FM transmitters/receivers are among the top favorite circuits of any electronic enthusiast. In this article/video, I have introduced a complete digital FM receiver design that has equipped with an LCD screen and three push-buttons. It can search for the FM signals from 76MHz to 108MHz manually and automatically (Scan mode). The signal strength is also displayed as a bar graph on the LCD screen. The output sound is amplified by a 3W+3W Class-D stereo amplifier that handles high-quality and strong enough audio power. As a controller, I have used the cheap and popular Arduino-Nano board. So let’s get started!
