Lecture 03: Project LED Blink Breadboard and Resistor

If you don't like to see ads while video is being played you can purchase this course for $200 from Udemy

In this lecture we learn to make our first project of Arduino. It is called Blink.

An Light Emitting Diode (LED) is connected with a voltage dividing resistor to Arduino and Arduino turns it ON and OFF in at different intervals of time. We will have control over time.
We learn how to calculate and select resistor for Arduino because we have Arduino boards workign with 5V and some board working with 3.3V so we have to know how to calcualte the value or resistor.

Also bread board is expalined and how to use it so student knows how to connect components in proper way for learning and prototying.
