and the emitter of the TIP127. This circuit pad is then wired
directly to 12 volts from the battery.
The Arduino Nano Joystick PCB
This PCB is quite simple. It only contains the Nano and
header pins to connect to the small joystick and linear
potentiometer. Since the linear potentiometer I had was
audio taper, I placed a resistor in parallel with the wiper
and ground end to produce a more linear change in
I also added a two resistor voltage divider so the
battery voltage could be read. The plastic box containing
this board also mounts the joystick, linear potentiometer,
power switch, and video output jack.
Both of the PCBs have places to mount additional
optional circuitry. These optional pieces are marked as such
on the schematic. This includes a header for an LCD display
on the joystick board and a header for a pressure gauge
and pads for an Adafruit 9DOF board on the controller
