A 3rd part to my tutorial videos on how to use the Lego Powered Up app for your Lego trains. In this episode the colour sensor is introduced and I’ve made a few short and fairly simple codes on the app to get the trains to do some cool stuff. I really hope this is of some use to you, if you don’t know much about Powered Up, and will give you the confidence to make your trains do more complex things. #lego #legopoweredup #poweredup #powerfunctions #legotrains #legotrain #legomoc #legomocs #legorailway #legorailroad #colorsensor #coloursensor
