The FM receiver module is based on the TEA5767 [1, 2] chip. It is a well-known module that could be controlled via the I2C bus. It covers the FM frequency range from 76MHz to 108MHz. At the output, it ...
The voice controlled arduino blinds project is a good example of IoT related project. It features an arduino nano and a HC-06 bluetooth module device that simplifies circuiting of the entire system.
This series of projects explore concepts of radio communications. We use LEDs to generate (very high frequency) radio waves and photo-resistors to take the place of radio antennas. These ideas are ...
