Let’s Kick Start

Time to move on, now……

It should look, something like this….

INTERNAL CONNECTIONS

Basics
Prototyping Boards
Power Supply

What are we going to discuss today ?

Why is it hard???

micro-processor vs micro-controller

Reff.. Voltage = 4.5V

How a Comparator works?

VOLTAGE DIVIDING CIRCUIT
