There is no better way to learn electronics and coding than building and programming your own gadgets. Adafruit has shared a guide that shows you how to make a Bluetooth volume knob for your tablet or smartphone with CircuitPython. It lets you turn the sound up and down, mute, and pause play from across the room.
In order to complete this project, you are going to need a Circuit Playground Bluefruit with Bluetooth, half-size breadboard, battery, and a few other cheap parts to complete this project.
