Hi Ytai,
Thanks for reply and sorry for the confusion. I plan to use this weight sensor with IOIO <https://lh3.googleusercontent.com/-DovYQ-cu_0A/WcHHVgmhvUI/AAAAAAAA9gU/zapvVE91XJ4gPelwMdvaWKxUhjjrU6WLACLcBGAs/s1600/22141909_52dcbe9c-2d96-456c-ad76-7df1487b1ce9_800_800.jpg> The item title is "(Load Cell) 20Kg + Driver HX711 24bit gain amplifier ADC Module" There is one illustration for connecting it to arduino <https://lh3.googleusercontent.com/-zxYvBoklcaE/WcHIvzNiA4I/AAAAAAAA9gg/ECSEqhvvl6867SeKvuemj0FdhOz53fG0wCLcBGAs/s1600/22141909_d3c60c0d-b9ee-40f4-b98c-207ad682d8cd_800_800.jpg> Based on this illustration, can I assume that I can just connect the load cell to the Driver, and connect the driver to the IOIO? Or I will need anything else? Maybe the "custom firmware" that you and Juan talking about. Thanks a lot.
