Using a Circuit Playground Express with CircuitPython's sound file and accelerometer support, we'll build a multi-voiced percussion instrument and blues chord progression player. Tapping the instrument will play the sound of a variety of selectable percussion instruments or step you through a blues chord progression one beat at a time. The project also includes a hack to connect the Blues Playground to a guitar amplifier for jamming on the big stage!
New to CircuitPython? Looking for an easy way to get started? We've written a library for the Circuit Playground Express that makes it super simple to begin using all the sensors, switches and lights. This guide will show you all the features of this library and how to use each one. Let's get coding!
Use the CRICKIT board with your Circuit Playground Express to control a cardboard animatroinc hand. Four servo motors pull the fingers into position using cable drive systems made from cord and straw guides. Program it all with CircuitPython to actuate as you press the capacitive touch controllers. You'll also learn to use the CRICKIT as an audio-animatronic controller with pre-programmed sounds and motions, such as counting in binary!
