What do I need?
I am told that I need some transitors. I have a 12v powerpack and 2 x12v motors. How do I set this up so that I don't blow-up the RPi and that I can control the motors through the GPIO?
I have a gertboard on the way but I would like to see if I can do it without it first.
I have little knowlegde about transitors and electronics but I do know how to build circuits.
Ok, here is my idea:
Using some of the set-up features that @aonsquared used with his Robot/Rover thing.
Using a 5 volt supply to power the Raspberry Pi and the Powered hub.
The Raspberry Pi will send commands to the Ardunio Eleven (which I still have to get), which will control the Two Motors through a H-bridge and PWM.
That camera will be powered through the 10 port hub, along with the Ardunio and the W/LAN dongle.
The Motors will be powered though a 12 volt supply (8 AA batteries).
All the commands will be sent through an Ad-Hoc Network to a Laptop running Windows 7 Pro 64 bit. I think that I will use by Joystick to move the Motors but I don't know how that is going to work as @aonsquared used a PS3 controller instead. (Saitek ST90 is the Joystick).
The LCD display will have the IP address so that I know exactly what it is whenever.
The Raspberry Pi will host a live webcam feed though an old Logitec Camera I have lying around.
One question is: Will PWM work on the motors through the Ardunio if I have the 12 volts going directly into the H-bridge Chip?
What do you think?
