CLUE Rock, Paper, Scissors Game using Bluetooth
Three versions of a rock, paper, scissors game in CircuitPython using Bluetooth Low Energy (BLE) advertising packets. These run on a CLUE or a Circuit Playground Bluefruit with or without a TFT Gizmo.
CLUE Metal Detector in CircuitPython
Metal detecting with a CLUE, a copper coil, a capacitor and a few other components in CircuitPython. The Circuit Playground Bluefruit with a TFT Gizmo can also be used.
CLUE Sensor Plotter in CircuitPython
Using CircuitPython to plot the all of the CLUE's sensors and display the voltages on the three analogue pads in a pseudo-oscilloscope style.
Circuit Playground Bluefruit Quick Draw Duo
A reaction time game for two Circuit Playground Bluefruits in CircuitPython using Bluetooth Low Energy to synchronise the boards and exchange reaction times. We're also do a scientific exploration of reaction times due to human biology and brain science!
Making oscilloscope images with DACs
Exploring image creation on cathode ray (analogue) oscilloscopes with single and dual digital to analogue converter (DAC) outputs in CircuitPython using the Circuit Playground Express and PyGamer boards.
Circuit Playground Express USB MIDI Controller and Synthesizer
Using CircuitPython 4 to turn the Circuit Playground Express into a USB MIDI expressive controller with a second program to make a USB MIDI-enabled, simple waveform, velocity-sensitive synthesizer using the onboard speaker.
Bluetooth Remote Control for the Lego Droid Developer Kit
Creating a Blutetooth Low Energy (LE) remote control for the Lego Droid Developer Kit using an Adafruit Feather M0 Bluefruit LE board to communicate using Visible Light Link (VLL) protocol with the Lego Micro Scout brick.
Comparison and Experimentation with Flammable Gas Sensors
An investigation and comparison of the metal oxide-based Hanwei MQ-3 and SGX Sensortech gas sensors using the Adafruit MiCS-5524 breakout board and Circuit Playground Express in CircuitPython.
Distance Measurement with Ultrasound
This project demonstrates how to interface the inexpensive HC-SR04 ultrasound sensor to a Circuit Playground Express. Microsoft MakeCode is used to explore the sensor's output.
