Micro:Bit coding is the perfect fit if your child is interest in electronics. Or if they may want to build robots or rockets one day. This little device packs very powerful capabilities: LED lights, speakers, a temperature sensor, a microphone, and even an accelerometer. Coding is done in a simulator that works just like the physical Micro:Bit. You don’t need the physical device to take the class. But if you do decide to purchase one, all of your class code will work perfectly on the device without any changes.
