This project is based on the microcontroller Arduino Nano 33 BLE Sense. Please don’t confuse it with the similarly named Arduino Nano 33 BLE! It is recommended to get the one with headers, so you can immediately start using it on a breadboard without needing to solder the headers on it.
This is the list of minimum required materials for Tiny Trainable Instruments
