I have a on going project to build a car-simulator and one goal is to get the feeling like sitting in a real racing-car. With this instruction I explain how I have build my pedals to my car simulator. Of course you can buy stuff like this but I want to build it cheap. My pedals have gas, brake and clutch and use a Arduino (Windows native drivers) to connect to usb port.
Hope I can inspire you with my building and I meet you on a trackday in Project Cars!
Step 1: Parts You Will Need to Buy or Get From Scrapyard
You can use any of board based on ATmega32U4
2. Usb cable between Arduino board and computer.
3. 3 piece Slide Potentiometer 5kohm.
4. 3 cheap styling pedals for cars.
6. Some metall to build pedal construction in
7. Nuts, bolts and cables to potentiometer
8. Project Cars or another car simulator you like.
Step 2: Welding Potentiometer and Arduino Together.
Connect Gas to A0, Brake to A1 and Clutch to A2.
Connect each potentiometer to +5v and GND
Step 3: Programming Arduino and Test
Install libary and open jenswsArduinoPedal project.
Download it to your Arduino board and connect to your gaming computer.
Go to Controlpanel/Hardware and sound/Devices and printer.
If everything is correct you now see your arduino board as a joypad.
Right click on your Arduino board and choose Game control Settings
After you choose your Arduino board you can go to tab test and test your potentiometer.
Step 4: Building Pedal Construction
I build my pedal construction in steel and welding it together. One tricky part was to find spring with correct feeling. You have to test what you like. I also fond that 100mm from bottom to center of pedal was a good length for my foot.
I show some pics how i have done to give you idea how you can build yours.
Step 5: Install Potentiometer on to Pedal Construction.
I have choose to mount my potentiometer in back of pedal console.
When I press on a pedal potentiometer go from 0 to 5kohm.
It may be a better solution to mount direct on pedal?
Step 6: Settings in Project Cars
Start Project Cars and go to Options/Controls/Edit assignments
Choose Throttle and press on gas pedal.
Do the same with Brake and Clutch
Step 7: Test Run in Project Cars
If you have done everything correct you now have som nice pedals to you car simulator.
Probably I gona build version 2,0 of my pedals.
I'm not 100% satisfied with the feeling in my pedals.
Maybe i rebuild brake to hydraulic and try different springs on gas and clutch.
