Code Recipes

Working code for every common project.

Hand-written, tested snippets for Arduino Uno, Mega 2560, Raspberry Pi, and ESP32 — copy them, wire your components, run. Every recipe is the same one our chat bot uses when you ask.

Tip: If your project isn't in the list, request a custom kit and we'll bundle the parts + write the sketch for you. For debugging code you've already written, paste it on our support page and our team will read it within one business day.
