Hello, I want to interface two weight scales. I could either purchase scales or build with FSR type sensor. Open to and appreciative of any ideas/suggestions.
Reason behind project: I have spinal chord injury and need to relearn how to sit with both feet having equal pressure on the floor. My idea is two pressure pads that I rest my feet on, and have display indicating when I am equal weight, and some indication of which foot is too light or too heavy. With this visual feedback I can train myself to sit. A bonus would be to have the scale useful at standing weight also, but that is in the future.
An old school analog version would be a rolling pin with a board on top that I tried to keep parallel to the floor. Perhaps I could fashion such and use strain gauge to feedback?
A more advanced approach would have a ball in lieu of a rolling pin to get 360 type feedback, but that might entail more than a starter project.
I have limited experience with Arduino, but plenty of programming/automation experience. I am looking forward to my first real project with it.
