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 it can keep accurate time for long periods, as is befitting a clock.

The Uno R3, with its 8-bit ATmega328P processor, has been a long-time favorite. But now, the Uno R4 is here to give a boost to your projects. Featuring a 48-MHz, 32-bit Cortex-M4 processor, abundant ...

This project uses the Arduino Uno PWM output to realize a fully isolated analog output with a range of 0..5 V or more. The use of an averaged PWM signal is not comparable with a real DAC, but it has ...

Now if we come back to the hardware feature the Arduino Uno R4 comes with 14-bit ADC, which is a huge improvement over the 10-bit ADC on the Arduino Uno R3. One another addition is the 12-bit DAC, ...

Both the Arduino Nano and Uno can be powered via their integrated USB connectors. This automatically supplies regulated 5V power to the board, allowing you to use any USB-supported power source ...
