I have been reading and testing different techniques now for three days , with now luck on replacing a load cell in a setup for use with a brake controller for a racing simulator. Where to start. Well i purchased some flexiforce 100 lb sensors thinking i could replace the load cell with one of these. I saw on Techscans website that someone was making a mod for this. I have set up the 100lb sensor on a breadboard and used it as a voltage divider , with good results. I've also got some sensors from bathroom scales and successfully set up a wheatstone bridge with results. I've set up a op amp set up and had results there also. Now what is confusing me is the voltage from the pcb on the brake board. It has three wires Red , White , And Black. On a multimeter when i test red and black i get -3.25 volts, when i test white and black nothing , when i test white and red i get + 3.25 volts. The only software i have is the calibration with the brake on my pc , but when i touch the red and white together the brake applies. Hope this make sense to someone , as you can tell i have little knowledge of electronics but a shove in the right direction would be appreciated. I've ordered an Audrino Uno also to help me resolve this
