Hi
I am working on a project to upgrade my brake pedal on my racing wheel setup. The position of the brake pedal is now being measure by a potentiometer, and the resistance is created by a spring.
I want to swap out the potentiometer with a load cell so the pedal input relies on the pressure i put on the pedal, rather than the position of it. This is better for a number of reasons.
Anyway, i can only put one load cell on it, and it has to be rather small. So i was thinking about the load cell SparkFun offers.(https://www.sparkfun.com/products/10245)
I've been doing some research and to my understanding you need a hx711 amplifier for a load cell to work properly. So i looked into that and all i can see is people using 2 or 4 of these load cells with these amplifiers to 'combine them'.
This is not an option for me. So i was wondering if you could use only one load cell with the hx711 board, or if i even need one at all if i'm only using one load cell.
Thanks in advance for your help.
