How to automate LEGO trains using original LEGO pieces (and Python)

In this video I show how to use PyBricks to program a train and a train car to use a sensor for automation. Hub-to-hub communication using Bluetooth is used to tell the cars when to open their doors.
LEGO Train used in this video: www.lego.com/en-us/product/ex...
Sensors:

and

Project for the code: github.com/LasseD/PybricksPro...
The code is written using PyBricks: code.pybricks.com/

For me, the most satisfying thing about these builds is that lego-snap. It has a nice ASMR feel.

I love how neatly you hid the electronics!

great video with the debugging!

3:20 This makes it more tricky. This is why h Corp trains are best.
Because they are not controlled by machines.
They are controlled by people.Instead of machines.

Great video! Nice combination of block-based coding and Python coding :)

Im surprised the switch wasnt automated, pretty cool though

[@LasseDeleuran]

That shall be fixed!

[@legomitroman]

👍

[@RohanBeckett]

awesome work - however I can't see the code on your github?

[@LasseDeleuran]

Thanks. I missed a commit. It has been added now.

[@RohanBeckett]

@@LasseDeleuran thanks for that! I'm working and learning both text and blocks coding - are you able to share the screenshot from your blocks code too?
