Programmable Power Supply (PPS)

Introduction
In laboratory and experimental work, the source of energy electric is very important.
Most products in electronics require using the current and voltage source. I propose to develop a programmable power supply as my senior project. The requirement I propose for this project is that the programmable power supply will provide the user an output voltage from one to fifteen volts at a current level up to 1 amp.
Description
For the user interface, the power supply will consist of a switch to turn the power ON or OFF; a green or red LED to monitor the power is ON or OFF, a keypad for the user to enter the desired voltage. An LCD display will show the correct information entered from the keypad, and the output terminal.
The figure below represents the programmable power supply.
