My final project is a rc car with a halleffect sensor sending data back to my control. The steps are to create an ISP covering Radio board, Populate a Fabduino, Modify the Fabduino in order to work with my needs, Program a new code that combines both the Node and the Motor codes, create two H-bridge boards, Program the Fabduino, and put all the circuits into the Rc car.
I have already created the ISP Radio board. My issue with this was that the radio I am using is a 3.3v radio while the Fabduino is running at 5v. I put a zenier diode on each signal connecting them to ground. By doing this I insure that all signals will only be 3.3v. I have discovered that a 3.3v zenier diode cannot handle 5 volts at usb amps. It caused an impressive burst of smoke. My solution was to put a 3.3v regulator instead.
I have programmed the code for the motor node. I have yet to test it due to a lack of a Fabduino that works.
I have populated and tested the two H-bridge boards. After minor debugging I have gotten both of them to work.
Due to a lack of time to finish I decided to build a switch for each motor and then just press the switch to turn the motor on. I made the switches so that they cover the ISP header. They use MOSI VCC and GND. MOSI will be connected to GND unless the switch is pressed which will then connect it to VCC.
I have accidentally fried my motornode boards. I decided it made more sense to run the Fabduino at 3.3v instead of 5v. This way I do not need to use zenier diodes.
