For this episode of Getting Started with micro:bit, we create a simple messenger app using the Bluetooth Low Energy (BLE) radio on two separate micro:bits. Afterwards, we create a light sensor that sends a wireless signal to a receiving micro:bit in order to catch a sandwich thief.

Great totorial, thanks. I also ordered one to my son. Stupid questions: What is the maximum pin current for "1" and "2" pins? Do they have transistor output, or its a direct CPU pin? If there are several hex-apps placed in a microbit folder, which one will be started? Is it possible to have automatic Arduino-like upload in IDE? Thanks.

This is some amazing stuff to teach children about the coming future of technology

Ugh this isn't better than teaching code! It's the same thing, stop with the click and drop interfaces, they aren't doing anyone any favors
