The project board below has been set up with a single input, the micro-switch. There are two outputs, both are LEDs. When the PIC microcontroller has been pushed into the LOW INSERT FORCE (LIF) chip holder the reset button should be pressed to start the program. The PIC microcontoller integrated circuit has been programmed to react when the microswitch, connected to input 3, has been pressed. As it is pressed, the signal created is detected by the program stored within the PIC microcontroller which switches on the output  LEDs.

The project board can have a range of inputs connected such as micro-switches, dark/light sensors, temperature sensors etc.... Outputs can include solar motors, LEDs, Bulbs, speakers etc....

QUESTION: Draw a simplified diagram to represent the layout seen in the diagram above. Explain each stage - INPUT - PROCESS - OUTPUT.
