...design a PCB board which would basically do exactly the stuff that I have drawn (please note that I would need a PWM on the stirrer as well, this is not present in the current wiring scheme). Everything written in green in the wiring scheme is in a different part of the prototype (ie in a physically different container, linked by a 5 way cable). The whole project is on a 12 V circuit apart from the two UV lights which need 38 V. Input is 12 V. Upon project assignment I will send the designs with the size constraints over. Aim is to have everything connect with JST connectors, the cable linking the two units being a MIDI cable. In a first step. would also need an input for connecting my PC to it as I will need to upload a program on it. Only bids which start with "I am t...
