Build an IR sensing hoop that displays your score on an LED matrix using CircuitPython.

Using CircuitPython, you can build your own 8-bit game using the displayio library. This game is based on the Chrome browser's jumping dinosaur game Easter egg. In this version, Blinka needs to jump over the Sparky the Blue Smoke Monsters to save the circuits running on CircuitPython.

Build a DIY guitar tuner using Adafruit PyPortal.

This project uses the CircuitPython BLE MIDI library to trigger a solenoid every time a NoteOn message is received. MCP23017 multiplexers are used to expand the outputs over I2C with the ItsyBitsy nRF52840 and ULN2308 darlington drivers are used to drive the solenoids.

Build a vibration bracelet that connects over BLE to trigger vibration motor with iOS notifications.

Get notifications from your mobile device in the form of vibrations using a haptic motor and Adafruit Bluefruit nRF52840 Feather.

A DIY step counter using the CLUE board programmed with CircuitPython. An optional 3D printed case and band help hold it to your wrist.

Build a CircuitPython powered MIDI controller! 3D print the parts to build a guitar that features strumming and a whammy bar!

Build a wireless 8-bit synth powered by the Feather nRF52840 and Circuit Playground Bluefruit. BLE communication allows the Feather to send packets with each button press. The Circuit Playground Bluefruit then plays the tones and swirls some NeoPixels after receiving the packets.

3D Print and build your own retro inspired weather station with PyPortal Titano and Circuit Python.

Mix traditional DIY and CircuitPython with this beginner woodworking project. NeoPixels are mounted inside this wooden Christmas tree shape and then controlled with a Circuit Playground Bluefruit that sits on top of the tree in a 3D printed star.

3D print and build your own motorized camera slider with Adafruit Feather and CircuitPython. Professional looking photography is a snap.

Create a creepy photo display that changes images based on the amount of light in a room.

The Raspberry Pi is an amazing single board computer - and one of the best parts is that GPIO connector! 40 pins of digital goodness you can twiddle to control LEDs, sensors, buttons, radios, displays - just about any device you can imagine. This Adafruit GPIO Expander Bonnet will give you even more digital deliciousness - 16 more digital input/output pins are yours for any desire you have.

Get up and running (tapping, free-falling, whatever!) in no time with this quality 3-axis, +/-16g digital accelerometer. from Analog Devices. It has more than one trick up it's sleeve too, with internal tap, double tap, motion detection, and more! Details in the guide.
