Different types of Arduino’s

Synopsis Arduino is a single board microcontroller based on a single

Integrated Circuit chip.

• There are variety of them, but this course will concentrate

on the Arduino Uno.

• The Arduino’s are open-source software open-source

hardware.

• They are widely used for education and hobbyists due to

low cost and availability.

Static Charge

Electronic components are sensitive to static chargesand needs to be handled carefully otherwise could be

damaged. Discharging of tactile surfaces that are going

to be in physical contact with these components is a

must for the safety and prevention of damage. For

these reasons we find that electronic components are

usually supplied in static envelops (pouches).

Installing Arduino

The Arduino boards need a development system where all the work is: performed; sketches (program or codes) are created and edited; compiled; and finally uploaded to the Arduino boards to be executed to conduct the intended tasks. To install Arduino software simply go to google and type the following:

<Arduino downloads>

The response will be something like this:

Choosing Board Type and Port

Exercise 1

void setup() {

// put your setup code here, to run once:

pinMode(13, OUTPUT);

digitalWrite(13, HIGH);

}

void loop() {

// put your main code here, to

}

void setup() {

// put your setup code here, to run once:

pinMode(13,OUTPUT);

digitalWrite(13,HIGH);

delay(1000);

digitalWrite(13,LOW);

}

void loop() {

// put your main code here, to run repeatedly:

}

Change to “LOW”

Exercise 2

Add Delay

Serial Port/*

Serial Port Usage

*/

void setup() {

// put your setup code here, to run once:

Serial.begin(9600); // define the Bps

Serial.print("The Mechatronics Engineering");

Serial.println("Would like to:\n welcome you all");

}

void loop() {

// put your main code here, to run repeatedly:

}

Control Charecter “\n”

Serial.println("The Mechatronics Engineering");

Serial.print("The Mechatronics Engineering");

Copy and paste the Serial instruction to the void loop

and see the outcome

Change to “print”
