I am building a small wireless controlled robot using the Arduino and the raspberry pi. It works by the user wirelessly connecting through to the raspberry Pi (using vnc or some other form wirelessly) and using the user inputs to send a command to the Arduino which controls the motorised wheels. SO for example if the user presses the up button, a 'W" command is sent from the Raspberry Pi to the Arduino which then reads it and pushes the wheels forward.
I was looking at the arduberry as a replacement instead of connecting a uno to the raspberry pi through usb, but I am not too familiar on how it work. Had a few question such as:
How exactly do they work (connection wise)?
Is it possible to write one python code in the raspberry pi that when run can load the specific ino code into arduino?
Sorry really new to the raspberry pi and need to find a solution soon so any help would be awesome.
