Today we finished putting together and calibrating the controller. The controller basically consists of a potentiometer joystick and a firefly node. It's all soldered together now (and I learned how to solder!) and ready to go. The only thing is, right now we have to power it from a power supply. Hopefully we can find a way to get power to the joystick from the Firefly.
Basic overview of our joystick:
-takes in ADC values for x and y axis
-converts this data into duty periods for the PWMs for each motor
-sends packets consisting of these duty periods to sister node
-car is stationary when joystick is at origin
-car moves forward, turns
-still cant move backwards; any motion of joystick in negative y direction gives duty periods of 0 (no motion)
