Sample Arduino Project To Learn How To Use Digital And Analog Inputs And Outputs

I assume you already know it, learning by doing is probably the best way to really sharp our understanding and skills, we just can’t replace experience with books. If you would like to really learn something than try it in the real world. Building an Arduino project can be a challenge.

But in the same time it will be also really fun and satisfying as we are building a working electronic system. so, during the next sections we will mix some basic theoretical background. with an actual project we will build and this will be the way to learn by actually doing and trying.




So to practice and learn some of the basic elements in Arduino we are going to build the following project in 3 main steps:

1. In step 1, we will add 6 LEDs and two simple digital sensors as pushbuttons.
2. In step 2 – we will add two analog sensors to control the LEDs speed and brightness, and in step 3, we will add a motion detector.

Looking on the circuit here we see first of all the Arduino Uno board and many external components connected to it. like the 6 red LEDs, two variable resistors, and a motion sensor on the left side. this project will help us to understand the usage of digital input, digital output and analog input. all connection between external components and the Arduino board is being done using a special prototyping board that is called breadboard

We will soon cover how to use this breadboard tool. Before we start, for building our project end-to- end this is the list of required components nothing here is really an expensive piece of a equipment, and if you already got some Arduino starter kit, as I mentioned in the first section, probably you are fully covered, but please check and verify that you got this list.
