Introduction

Connecting a headphone jack to a Crazy Circuits project allows you to attach computer speakers or headphones for sound output.

Video Overview

  1. No matter which Crazy Circuits programming board you use, they can all make sound. Using our Piezo Speaker is the simplest way to hear something. Connecting it with a few pieces of Maker Tape is quick and easy. If you want to use powered computer speakers, headphones, or anything else with a 1/8" audio connector, the Headphone Jack is the perfect solution.

    • We recommend connecting the Headphone Jack wires to a Crazy Circuits Screw Terminal. All you'll need is a small slotted screwdriver.

    • Polarity won't really matter when connecting the wires. It's also worth noting this is a mono (not stereo) audio connector, so you'll only get sound from one side of a headphone or one side from a set of stereo speakers.

  2. When connecting to a Bit Board with a micro:bit the default connection will be to Pin 0 and GND. (Don't worry though, defaults can be changed!)

  3. If you are using a micro:bit V2 it does have an on-board piezo speaker, which you can turn OFF in your code.

    • You can also specify the pin used for audio output. (If you do not specify one, Pin 0 will be used.)

  4. For the Robotics Board just connect to GND and any digital pin.
