Peter-CAD-HST im doing some research on the same topic i have all of the hardware (nano, solenoid, tp120, and pressure sensor (mpx4250ap)) with a oled display. Im wanting to set up a boost controller with closed loop pid control to have a adjustable target pressure with rotary pot resistor and have the display with simple duty cycle % and pressure reading
