Arduino microcontrollers have added Python to the range of compatible programming languages. Others can be used, and not just Arduino's own IDE app.

If you’re a programmer with a knack for making things — like Simon Boak — you custom build a replacement. This is the SB116, an 8-bit programmer’s calculator powered by an Arduino Nano.

The Arduino Nano 33 BLE Rev2 is a significant leap forward in the world of microcontroller boards, designed to empower a diverse array of projects with its advanced capabilities.

The hardware itself is pretty straightforward. There is an Arduino Nano to run the speech recognition algorithm and a MAX9814 microphone amplifier to capture the voice commands.

Ok, we’ll come clean. [Design Build Destroy] didn’t really add any memory to his Arduino Nano. But he did get about 1.5K more program space when compared to the stock setup. The trick? On some ...
