Introducing the Arduino

The Arduino is a small development board with a brain (also known as a microcontroller) that you can program. It interacts with the real world through LEDs, sensors, motors, LCDs, buzzers, etc...

If you type on your search engine the query “Arduino projects”, you will find tons of amazing Projects.

What’s an Arduino?

Arduino is essentially a tiny computer that can connect to electrical circuits. The Arduino Uno is powered by an ATmega328P chip, it is the biggest chip on the board as you can see on the picture below. That’s where you store your programs.

Arduino UNO R3 board with ATmega328P – (Click to see on Amazon http://amzn.to/YMjlZg )

The top row of the Arduino has 14 digital pins, labeled 0-13. These pins can act as either inputs or outputs. You can connect them to your circuits to turn them on or off. You can also read buttons – see if a button is either pressed or not.

Downloading the Arduino IDE

You can load new programs onto the main chip - ATmega328p - via USB using the Arduino IDE. Visit the link below to download the latest Arduino IDE:

 http://arduino.cc/en/Main/Software

I won’t go into much detail how to install this software, since the official Arduino website does a great job explaining how to do it any of the three operating systems (Windows, Mac and Linux).

In the end, you should see a similar window on your computer.

Uploading an Arduino Sketch

Connect your Arduino UNO to your computer via USB.

For this example you will be uploading the most basic example that the Arduino has. Which is blinking an on-board LED or digital pin 13.

Open your Arduino IDE.

Go to File > Examples > 01.Basics > Blink

By default your Arduino IDE comes pre-configured for the Arduino UNO. Left-click the “ Upload ” button and wait a few seconds until a “ Done uploading. ” message appears.

Ultrasonic Sensor with LEDs and

buzzer

View Project on Random Nerd Tutorials Click^ here Watch on YouTube Click here View code on GitHub Click here

Introduction

In this project you have an ultrasonic sensor that measures the distance and the LEDs bar graph will light up according to your distance from the sensor. As you get closer to the sensor the buzzer beeps in a different way.

This circuit can work as a parking sensor!

Parts Required

 1x Arduino (Click to see on Amazon)  1x 74HC595 8 Bit Shift Register  1x Breadboard  8x LEDs (for example: 3x red, 3x yellow, 2x green)  9x 220 Ohm Resistors  1x Buzzer  1x Ultrasonic Sensor (for example: HC-SR04)  Jumper Wires

Arduino Poor Man’s Oscilloscope

View Project on Random Nerd Tutorials Click^ here Watch on YouTube Click here View Arduino code on GitHub Click here View Processing code on GitHub Click here

Introduction

In this project you will create a cheap oscilloscope with an Arduino and a few lines of code! I've found this project on the internet a few months ago, so I don’t know exactly who wrote this code (I think it was Sofian Audry according to the processing code).

Let's start!

First, download Processing software. It's free Click here to download. You don't need to install anything; it runs just like the Arduino IDE.

Upload this code to your Arduino

#define ANALOG_IN 0

void setup() {

Serial.begin(9600);

//Serial.begin(115200);

void loop() {

int val = analogRead(ANALOG_IN);
