**I was sick for the second week project, so I was actually behind in terms of adding on to make the Bluetooth work. I ended up doing the remote controlled + the bluetooth part together in one week.
(Also, my cover image wouldn't load for some reason. That's why I have no photo for the cover.)
I found a very helpful detailed description of the H Bridge I was using here (along with sample code for running DC motors): H Bridge description
Equipment used: Laser cut Body (2 pieces); laser cut wheels, 2 dc motors, breadboard, arduino, H Bridge, 9V and 12V battery pack, bluetooth chip, phone that can download BLUE fruit, lots of wires, double sided tape, hot glue, super glue, rubber bands, and zip ties.
For the wiring, I followed and combined tutorials from the nRF8001 Tutorial and the tutorial for wiring DC motors with the H Bridge.
The final code I used was the callbackEchoModified file given in class.Difficulties:
- Remembering to use the enA and enB output pins for the H Bridge ( needed for PWM on DC Motors)
- Creating the final shaft and laser cut wheels for the back. Main problem was finding bearings and something that would fit snugly on the shaft.
- I forgot to switch the weight distribution so that most of it was over the motors.
- Also, had had minor issues with battery pack connectivity.
