MICROCONTROLLERS POWER SUPPLY

Any microcontroller needs a powersupply to work,the supply must give constant

a constant output voltage.for all our microcontrollers we need a 5V supply.her

e is a simple circuit which gives a regulated supply voltage.and we constantly

use this in our every microcontroller project.

EXTRA READING:

1.prefer to use 1Amp trasformer,as many can be connected to the single supply.

2.you can also half wave rectifier instead of a bridge rectifier,just modify

the rectification section.

3.a 7805 ic used here gives out a constant supply of 5V

4.the capacitors used there are for smoothening and

avoiding unwanted ripple.
