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 Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.

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, ...

One of the great things about the Arduino environment is that it covers a wide variety of hardware with a common interface. Importantly, this isn’t just about language, but also about abstrac… ...

We've got an exciting new book about the equally intriguing Arduino Uno R4. It is based on a 48-MHz, 32-bit Cortex-M4 processor with an ample amount of SRAM and flash memory. Plus, it features a ...
