I have very limited knowledge of electrical engineering and mechanics (I'm hoping to learn) so please forgive me if this is a stupid/noobish question.
I've been thinking about making a steering wheel and pedals for PC racing and sim games. I can't afford or justify paying the money that Thrust Master and Logitech want.
I've seen a way of doing the basics of what I want by hacking a control pad; extending the buttons by soldering some new wires to lead them to where I want. The pedals are giving me some trouble though. I'm hoping you guys can help me with this theory so I can understand how things work.
It looks to me like the pedals use a potentiometer mounted sideways so that as you press the pedal further down, it increases the speed. What I can't figure out is how that works. Its the top part of the pot that twists to vary the current (is current the right word here?) so how does a pedal that goes up and down, turn something that twists left to right?
You can see what I mean in this video: https://youtu.be/hzqB1ZTcAME?t=216
I'm not ready to build anything yet but I like to understand the theory so I have a better idea of how to build what I want.
Any help is greatly appreciated :D
