This project requires hardware/firmware design of a digital interface/control circuit to an existing analogue circuit.

We have an existing operating analogue design which needs a manual adjustment via a 2W potentiometer to operate.

The concept is to replace the potentiometer with a digital alternative (FET Controlled resistor) controlled via a microprocessor (PWM).

The Microprocessor will read in AC Voltage and current to determine the Potentiometer value as required.

A Microchip PIC is our microcontroller of choice, but we are open to alternatives.

We have tested the concept the concept with varing success and now require the "polished version"

Key constraints are power rating of the potentiometer, as there is a large inrush.

Project will be split into milestones to ensure project is delivered currently.

Experience with Main Voltage a Must

Full details will be provided to success candidate.

NDA will be required for successful candidate.

Please feel free to ask questions, and we will attempt to answer them at this early stage.
