Hi There, I have almost 13 years of experience. I have read the details and have a few questions. Please get back to me to discuss it further. Thanks.
I suggest you to use a micro controller to do this task. Are you familiar with Arduino platform? IF you can make the case and PCB, I can design the program and the circuit diagram
Hi I have read your requirement and I can design a PCB board for you and encase it in a custom created 3D box. I will design the board on Altium Designer. Kindly Inbox me for further discussion
