    I'm creating a Motor Operating Valve (MOV) and need a professional to design the PCB and develop embedded software for it. Key Requirements: - PCB Design: The PCB design should accommodate 20 Digital Inputs and 10 Digital Outputs. - Embedded Software Development: I need an expert to develop the required embedded software for the microcontroller. The software should be able to efficiently control the fluid flow through the MOV. Ideal Candidate: - Experience in PCB design, especially with microcontroller-based projects. - Proficiency in embedded software development, ensuring smooth operation of the MOV. - Prior experience with fluid control systems would be a plus, but not essential.
