$250-750 USD

Paid on delivery
Need help designing and building a controller circuit using a microcontroller. The circuit runs off of 110 AC mains power and essentially controls motors in response to user-selected pre-set values (low, med, high), and a handful of sensors such as safety shutoff sensors. This project is NDA-protected, and so our NDA agreement will have to be in place before discussing the specifics of the project any further. Good luck and have fun!
