All 10 Real Projects You Can Build

Every project below is buildable entirely from this kit's parts, no extra purchases needed. Photos of finished builds are shown further down this page where available.

Build an Ultrasonic Theremin

Wave a hand closer or farther from a sensor and hear the pitch change in real time, a real musical instrument built entirely from a distance sensor and a buzzer, almost pure software creativity.

Build a Capacitive Touch Piano

No moving parts, no mechanical switches, just touch a pad and hear a note. A real capacitive-sensing keyboard built from touch modules and a buzzer, teaching genuine touch sensing instead of a simple button press.

Build a Digital Compass & Tilt Display

Point it and watch a real heading track live on screen, real orientation sensing, the same class of sensor behind a phone's own compass and auto-rotate.

Build a Distance Warning System

A real ultrasonic sensor and a buzzer -- point it at something and get an audible warning the closer it gets.

Build a Reaction Timer Game

Wait for the signal, then hit the button as fast as you can -- a small display and a stopwatch built entirely out of your own code.

Build an RFID Access Demo

Tap a card, unlock something -- the exact same technology behind a hotel key card, built and coded by you.

Build a Home Status Display

A small screen that always shows the one thing you care about — build your own flexible status board and decide what it tracks.

Build a Smart Plant Monitor

Learn how a capacitive soil sensor tells a controller exactly when a plant actually needs water, instead of guessing.

Build a Mini Weather Station

A local temperature and humidity readout you can build in an afternoon — no cloud account, no app, just real numbers on a real screen.

Build a Room Temperature & Humidity Monitor

Learn how a controller, environmental sensor and small display work together to measure and show room temperature and humidity in real time.

A Note on Availability

A couple of items in this kit occasionally sell out given real demand across our catalog. If something's temporarily out of stock, it's shown that way here rather than hidden -- we'd rather you know than guess.
