I do not have any Raspberry Pi experience.
I can connect to my Raspberry Pi Zero W with ssh and Remote Desktop. The Raspberry is connected to a motor controller called 'Sabertooth 2x32'.
The Sabertooth has the ability to be controlled via serial input through its USB port. The Sabertooth has its own power source.
The bot is a lawnmower. I currently control the bot via RC through the Sabertooth. It works.
But now I would like to control the bot from the Internet.
But how do I send serial commands to the Sabertooth from the raspberry? It seems USB from Raspberry to Sabertooth would be simplest. Don't have to mess with the GPIOs then.
But...I just do not know where to start. Are there any apps I can install that would do this? Like a web server for the raspberry that would allow me to live stream my camera and use like a virtual joystick to control the bot? Maybe an Xbox controller from my PC.
I apologize for my lack of knowledge; and I have been googling. If you just want to drop a link to get me started that's cool
