Microbit Express 3.5(Controlling multiple trains)

A few weeks ago The Micro:bit Express got an upgrade with a new motor controller from 4tronix Read more here(link). Two weeks down the line I bought another one as I was so impressed with it. Now I have updated the code for the remote control to use the pins to allow independently remote control two separate Lego Trains. You can see a brief but shaky demo of this working below:

Again I have used MakeCode editor link

Below are the hex files for the two trains and the remote control.

You will need:

•  Three Micro:bits
• Two Lego Trains 
• Two 4tronix motor controllers 
• 2 6 volt battery packs to power the motor controller and the Micro:bits.
