Guide Update: CircuitPython Essentials – Audio Out
Use CircuitPython 3.0 and your Express board to play audio through a headphone jack!
CircuitPython 3.0 has an updated audio module that allows you to easily play generated tones and wave files through a headphone jack. We’ve written up a guide with two CircuitPython examples – one for tone generation and one for wave file play, pause, and resume. There’s a list of steps and wiring diagrams to help you wire up your M0 or M4 Express board to a button, a potentiometer and an audio jack. Once you’re set up, you’ll be able to play a tone at the push of a button, and play, pause and resume wave file playback. These simple examples can easily add audio to your projects. Have fun with it!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
