In order to write and edit code, you'll need a text editor. You can use any one you'd like but the easiest editor to use in conjunction with the Circuit Playground Express is called the Mu Editor. It has built in functionality to receive immediate feedback from the Circuit Playground Express's serial monitor. This means it's super easy to find problems with your code. Follow this short guide to install and run the Mu editor on your computer.
