Arduino Synthesizer plays Westminster Chime
You may already know the tone() function from the Arduino Library. But this simply spits out a square wave and so it sounds rather boring.
But with a simple trick we can generate any waveform with an Arduino and a small circuitry, and with this even imitate musical instruments!
In this project, I use the Timer/Counter 2 of the Atmega 328 MCU to generate a PWM signal. After low-pass filtering with some resistors and capacitors, we get either a sine, sawtooth or rectangle wave with programmable frequency and duty cycle. By modulating with an ADSR Envelope, it is even possible to imitate any musical instrument and play a small tune!
You can download the schematic and example code from here:

breadboard-fm-radio-with-rda5807-and-wio
This is a complete FM receiver circuit based on the single chip receiver RDA5807. The WIO Terminal controls the chip over the I2C protocol and offers a nice user interface built on the LVGL library. It has a wide frequency range (50-108MHz) even outside the public FM broadcast channels, offers automatic scanning and RDS/RBDS.
