What also sets the RP2040 apart are its two built-in features: a real-time clock (RTC) that provides accurate date and time, and a voltage-dependant temperature sensor. The Arduino Nano and ...

The buttons are operated using an Arduino Nano RP2040 Connect module programmed using a custom sketch. This allows the buttons to act as USB input which makes it easier for the PC to read for input.

For instance, the ATMega328P code is written in Arduino-supplied C++, but ESP32 and RP2040 in particular used MicroPython, which does more than just running the code, and MicroPython for ESP32 in ...
