Load cell on Xbox - lever for disabled gamer

Other Hardware Product Design
1

Hi everyone!
I’m Adam and I’m quadruplegic. I really want to play cars on Xbox with load cell lever and this is my project. I’m ultimate beginner and never used codes.
Lever is for throttle and brake (push - brake * Positive values), (pull- throttle * negative values). I don’t need to have load cell calibrated for accurate weighing.
Initial value up to e.g +3000 for brake, Initial value up to e.g -4000 for throttle. Different stiff spring on each side of load cell that’s why different 100% values on each side. And brake values send to channel one on digital potentiometer, throttle values send to channel 2 on potentiometer.
Chain: load cell - hx711 - arduino uno R3 - MCP42010 - two 3.5 jacks - Xbox adaptive controller.

THANK YOU ALL for helping me to achieve this project!:smiling_face:

Is the load cell required? Would a joystick allow you more input (forward, backward, left, right)?

I already have the lever with load cell. Ofcourse, the easiest way is lever with analog pot, but I want to use load cell. I have all Components on picture. Now I need help to code it.:smiling_face:

How much programming do you know?

Have you read about the HX711 and MCP42010?

If you install a HX711 or MCP42010 library in your IDE, both will have examples.

This page gives example sketches for the HX711.

Code for HX711 works great, now I need send data from hx711to dual digital pot. From -100 to -4000 to pot1 and 100 to 4000 to pot2.

Your digital pot might have a library with examples. Use the model number with ".h" suffix to find the library (example: hx711.h). Multiple libraries would mean examining them for the best fit for your project (look at the examples, run the examples, et c.)
