Interested in the Internet Of Things (IoT) then use a Bluetooth Claw with FlowPaw and go wireless!
Here we have made a rover that can be controlled via FlowStone, in the beginning we use an Xbox controller to drive the rover around, then switch to Autonomous Mode and let the rover drive itself using IR distance sensors to avoid obstacles!
All of the decision making (code) runs on the Laptop so you can literally edit the code as it drives around!
