Guys, looking for some help
We have a slot car set that uses the wired rheastat type speed controllers. What I would like to do is replace that with wireless units, and my thinking is that I could use 4 of these http://www.amazon.co.uk/Zeemote-Bluetooth-Mobile-Gaming-Controller/dp/B002GP7OBU
as wireless 'joysticks' and use one axis of each to control a lane. Windows 7 accepts multiple input devices.
Is there some way of using one axis from each unit and assigning one of the arduino outputs to it? It would require simple speed control, either via variable voltage (0 to 22V) or PWM. I am assuming that the Arduino can modulate the voltage provided by an external power supply? Essentially the Arduino would be hard wired to the PC, which would act as the interface between the controllers and the board.
The output would be just a linear output between min and max, but as stated above would have to be from 4 different joystick units so that each player is independent.
I have not yet bought any hardware because I am not sure if it is possible. If there is an alternative way of acheiving this, I am open to ideas
Thanks for your thoughts and ideas
