Instead, he drew up a simple schematic that used an Arduino Nano, an FM radio module based on the TEA5767, and an audio amplifier based on the LM386. A single button on the Arduino helps cycle ...

so whipped up a neat design using analog meters to display the time. The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so ...

and TFT display module. The I2C/TWI pins on the Micro are on D2 and D3. For Arduino beginners, these two boards are nearly interchangeable, especially when used in simple circuits like the Arduino ...
