A picture of a variable resistor is shown below. Start by connecting to the leftright wire and ground and with your variable resistor turned all the way to the right. With the wheelchair safely elevated to prevent movement or with the operator safely in the seat with room to drive around connect the variable resistor while taking notes. K ohm is a good start and connect a wire to its center and left terminal. To determine resistor values, start with a variable resistor a 1. K resistors are to pull the transistors inputs to their default state, so the joystick works normally when nothing is plugged into the interface boards input side. Emotiv Research Edition MiamiIn actual practice as you can see by looking at the schematic and the actual circuit the resistor values have to be chosen to achieve values which will not cause the wheelchair brain to think there is a malfunction in the joystick.

V diigtal controller like the PC parallel port or 8 pins of an Arduino control the 1. This is an easy way to let an eight bit TTL 0 5. When these transistors are turned off, the resistor is no longer pulled toward ground and the joystick wire gets pulled toward the 1. These transistors are normally on, and their drain terminal is connected through a diode to the forwardbackward or leftright wire.

The other four transistors are connected between ground and a resistor to the 1.

Another two transistors are used the same way for the leftright wire. When both transistors are turned on, both resistors are pulling toward ground, representing maximum speed in that direction. One has a larger resistor and the other a smaller one. Two of them pull the forwardbackward wire toward ground through a resistor each. 0 are FETs, they draw no current although their default mode resistors take a milliamp or so so they can be driven from any digital control signal. All of these parts can be found at mouser. It does this using transistors, some diodes and a bunch of resistors. Steps with PicturesThe interface board takes eight control lines in, from an Arduino or a PC parallel port, and can make the wheelchair think the joystick is being moved. This Instructable will show you how take a Radio Controller Helicopter and modify the remote control hardware such that it can be operated by free, open source.
