I want make PID controller for boost (step up) by using PIC I need cood ;and connection please o/p voltage 20 v

Hello,

Here is a circuit to boost 5v to 20v. All you have to do is change the resistor values:

thank you colin55 but what about the code and what do (red green yellow and orange) mean???and my boost is not like that it's basic boost consist of diode and capacitance and inductance and transistor

If you notice, colin55 has shown a 3v to 5v converter being used to supply power to a PIC - the colours are just part of the application it's being used for. The PIC isn't part of the converter. You have to modify the circuit to supply 20v from your 5v input.

Personally I wouldn't attempt PID control using a microcontroller - it's too complicated: https://en.wikipedia.org/wiki/PID_controller
