Small PID with Pt100, Pt1000, Thermocouple or 4~20mA (1~5V) input. Single output with Choice of proportional (PWM) or On/Off Output. 2 x 4-digit LED displays + ancillary LEDs, simple 3-button menu with basic PID settings only. Other more complex projects to follow - pending cooperation on this project. Must show an understanding of what is required and track record on working with PIC and/or Atmel.
