Remote work for a programmer. You need to write a program for AVR Atmega8 DIP28 (all source code (with detailed comments), a ready-made firmware file). Configuration of -4(5) analog inputs, 1 with voltage tracking. The task is to change the state of the inputs to control the shim. Smooth manual adjustment (potentiometer) with a filling factor (Dute cycle) with a frequency of 0.5 Hz to 2 Hz. Preferably at Atmel Studio. There is a scheme available in Proteus. There is a ready-made iron without a program
