I have been wracking my brain over what to do next. It is a tale as old as time. Someone creates a fantastic python program that looks like it will solve all your woes but it turns out to be a headache to implement because of one reason or another. Hub2Hub repository was once such a headache. The repository is filled with a lot of great information, but unfortunately, I could not get the demo that utilizes the Lego Hub and a Raspberry Pi Zero.

Later I decided to establish a serial connection between the Lego Hub and a Raspberry Pi Zero. I found a great website that outlined what each pin in the Lego Hub ports was for. I was able to establish a connection but data wasn't transmitting and receiving correctly. I tried everything I could think of to fix the problem but at last, this seems to be a dead-end for now.

I will look for another solution.
