FM Radio Receiver Using Arduino

At the heart of today’s project is the cheap TEA5767 FM radio module. This module comes with all the components required to build a FM radio receiver, all on board. The module is based on the TEA5767GH which is a single-chip, electronically tuned, FM stereo radio for low-voltage applications with fully integrated Intermediate Frequency (IF) selectivity and demodulation. Through an I2C interface, the module can be connected to Arduino to digitally control its tuning frequency and other characteristics, giving room for opportunities to digitize some of its operations.

For this project, we will connect the FM module to Arduino , so we will be able to set its tune frequency, display its signal strength, current frequency, stereo mode and other. The Nokia 5110 LCD will be used as the system’s display, providing visual feedback to the user while potentiometer is used to set the frequency and volume of the radio receiver. Turning the knobs in one direction will increase the volume or increase the frequency (depending on the particular knob being turned) and vice versa.

Project customization is also available.
