For example: :įor the digital mode, the digitalHandbrakeSwitch variable is used to set the level at which the handbrake is considered to be engaged. To select the operating mode, uncomment the line of the mode to be activated, and comment the mode to be deactivated. when i connect both the wheel + the handbrake I can calibrate the wheel but i cant calibrate the hand brake. The connection between the handbrake and the pc is made by an Arduino Leonardo, as for the SRT pedals. hi all, im making a 'handbrake' for my PC to play games with my G920 wheel, but im having some conflicts. The simus compatible with the analog mode are (non exhaustive list):įor the others, you can use the digital mod. The handbrake can be used either as a analog axis or as a button. 1 Banjo UNF 3/8-24UNF ( Aliexpress, Ebay) that goes on the master cylinder.1 Banjo M10x1.25 with pressure sensor mount ( Ebay) (goes between the brake calipper and the pressure sensor).Handbrake : ( Amazon, Aliexpress, Ebay).Brake caliper : Single piston (A) ( Amazon, Aliexpress, Ebay), Double pistons (B), 4 pistons (C).Cables 3cores 22awg (outer diameter is 4mm).Hydraulic pressure sensor 500psi 1/8″ NPT ( Amazon, Aliexpress, Ebay).If you push EXTREMELY hard you might consider using a 1000 psi sensor.The calipper mount is available on Thingiverse. The feeling is just perfect, and it is perfectly consitent with the brake pedal feeling. The applied force is captured in the hydraulic circuit by a pressure sensor. The handbrake is connected to a brake caliper. However, I am looking for a company that could produce plastic parts for those who do not own 3D printers. That would be trading, and I am not, and do not wish to be a trader. You want to support this project ? Summary:įor info: I do not sell ANY PEDALS OR PRINTED PARTS. It is directly compatible with the SRT gearbox. What Im using: Teensy 2.0, Potentiometer and my good ol windows 10 computer. The Project: Make a pressure sensitive handbrake for my racing simulator because no one sells them. My PCB is a bit different but it still uses the Atmega32u4 and registered as having an Arduino Micro Bootloader in the control panel.The SRT P1 hydraulic handbrake is based on the same principle as the hydraulic brake pedals: a brake caliper is actuated by a hydraulic circuit in which the pressure is measured. Hey guys, very new to this arduino thing, doing my best to figure it out but Ive hit a wall. If not then hopefully this will help someone else. I've just resolved it so if either of you are still hanging onto those broken handbrakes, this should help. Move out of that case original electronics so testing will be easy.īTW, if you don't have one already – get a simple magnet, any will do – this is a hall sensor – it measures magnetic field and according to it strength sensor sends voltage from 0v to 5V back to Arduino. Get/borrow/steal a simple multimeter and I will help You to troubleshoot it. Your original sensor is bent, it should be like that?Īgain, my suggestion is to troubleshoot Your old electronic – it will be way easier. You can plug old sensor to new Adruino and check if it work, if so – most likely Arduino is faulty. In the code, in line "int sensorValue = analogRead(A0) " change "A0" to "A2" and upload to Arduino, open serial window (magnify glass icon on top right) and You will see sensor value. To make that sensor work is very easy – in Arduino IDE go to file>Examples>01 Basics>AnalogReadSerial. You did not post picture of original Arduino – remove it entirely, plug it to computer, take a picture of it while it's plugged and upload here. Tho I recommend checking all wiring and contacts first of Your original electronics – Arduino Pro Micro do not dye for no reason, it's very likely a failed USB cable.įor more help please post high resolution pictures of internal electronics. As a last measure You can desolder chip from original board and put it on Your new Arduino Pro Micro – it should work if You make all the connections right and will not fry the chip in the process. To make it work with default drivers will not be easy or even impossible due to proprietary code manufacturer used. If you can't fix it and want to replace electronics – it's easy.ġst You need to hook Your sensor correctly and get data from it to Arduino.Ģnd You have to make Your Arduino Pro Micro as a HID device. I recommend You to replace USB cable first, it's a big chance that it will work again. If it gets 5V that means that it's sensor or wire to sensor issue or USB data wire is broken. First – if You can't figure out why your toy broke in a first place I don't think You are able to fix it But I'll try to help – check wires first, check if internal electronics gets 5v power from USB, it might be simple connection fix.
