Simulators are digital versions of the sensors/components to allow you to test everything directly in MakeCode
In the past, to test your code from MakeCode that interacted with any kind of hardware (like a motor, dial, button, LED display, etc.) you would have to:- Code your project
- Download the code to the micro:bit
- test and see if the code is working
You would often have to do this several times over and over again until you got your code just right.
With the simulators, you can now test your code solely within MakeCode so you and your students can be confident it will be working the first time and allow you to re-capture that precious time.
MakeCode recognizes what sensors/components are connected to the Breakout Board and the simulators will automatically appear just under the micro:bit simulator.
