in reply to Controlling USB on Raspberry Pi

It's been a long time coming due to the Pesky Pandemic and not being able to visit our uncle to install the curtain controller. All that time it has sat by my partner's desk clicking away to itself twice daily. But now it is installed in its new home and connected to the electric curtains...

Video proof of it working!

A big thank you to everyone that helped me create a curtain controller for a blind man who, obviously, doesn't know when it is dark. He is delighted with his late Christmas present.
