Let's Make Robots!


Arduino Fio, I2C, GPS and motor issues

Anyone else using one? It is sort of an odd choice for robotics, but I got one for a project that it didn't work out for. The built in xBee support doesn't work with the 900 Pro. It's a power problem - it has too little. But I am powering it with 6v to its VIN from a BEC, so it was simple enough to daisy chain a couple of diodes from the BEC to a breadboard to give me 5v that I can power components with. I have a GPS and compass on the breadboard. I currently have Bluetooth on the hardware serial line and I am controlling a motor with ESC and a servo for steering my RC truck chassis.
