Step by step example of stoplight program with code

1. ARDUINO ENVIRONMENT
TUTORIAL
LAST PICKS

2. INTRODUCTION TO ARDUINO
• Open-source electronics platform (original source
code is freely available to be redistributed and
modified)
• Arduino Boards: microcontroller that reads input
and turns into outputs (i.e. finger on button turns
on an LED light)
• Instruct Arduino Board using Arduino Programming
Language and Arduino Software (IDE) communicating
through the board’s microcontroller
• Void setup() & Void Loop();
[1]

3. ARDUINO UNO
• Microcontroller with:
• 14 digital inputs
• 6 analog inputs with 10-bit resolution
• Can be:
• Purchased on eBay for $6
• Programmed in C
• Interfaced to a computer through USB
• Interfaced to many sensors
[3]

4. TUTORIAL: SETUP
• Buy Arduino UNO board from Adafruit, Element14, or another
Arduino Distributor
• Download the software in this link:
https://www.arduino.cc/en/Main/Software
• Buy a starter electronics kit for building circuits (Optional):
https://www.amazon.com/16Hertz-Electronics-Breadboard-
Resistors-Raspberry/dp/B00J4RN61A
• Launch downloaded software - Arduino IDE

5. TUTORIAL: INITIALIZING
• Click on Arduino Uno in the
Boards
option under the Tools tab
• Begin writing program:
• Example shown later

6. TUTORIAL: UPLOADING TO BOARD
• Save your code
• Connect the board to the PC through the microcontroller and USB
port
• Upload to Arduino board by clicking the arrow
• Provide Power to the Arduino board to run indefinitely
TUTORIAL: SHUTTING DOWN
• Remove Power Source to stop the program
• Exit software anytime after upload to board

7. AN ARDUINO EXAMPLE
Stoplight
[2]

8. CODE
int red = 10;
int yellow = 9;
int green = 8;
void setup() {
pinMode(red,OUTPUT);
pinMode(yellow,OUTPUT);
pinMode(green,OUTPUT);
digitalWrite(green,HIGH);
Serial.begin(9600);
digitalWrite(green,HIGH);
Serial.println("Begin green
light");
delay(2000);
}
void loop() {
changeLights();
delay(3000);
}
[2]
void changeLights(){
Serial.println("Light Changes");
Serial.println("Yellow");
digitalWrite(green,LOW);
digitalWrite(yellow,HIGH);
delay(3000);
Serial.println("Red");
digitalWrite(yellow,LOW);
digitalWrite(red,HIGH);
delay(5000);
Serial.println("Green");
digitalWrite(yellow,LOW);
digitalWrite(red,LOW);
digitalWrite(green,HIGH);
delay(3000);
}

9. ARDUINO IN INDUSTRIAL ENGINEERING
• Arduino-based data acquisition
• Interfacing Arduino to Excel, MATLAB, and
LabVIEW
• Arduino-based tensile tester
• Tensile testing done to measure
mechanical properties
• Two parameters measured
• Load applied to sample
• Sample’s extension
• Reprogramming the robotic arm using
Arduino
• Project designed to sort glass and non-
glass waste
• Arm controlled by Arduino microcontroller
• Optical sensor used to distinguish between
parts
Tensile tester wiring
configuration for 5 kg load
cell and ultrasonic sensor

10. OTHER ARDUINO APPLICATIONS
• Break timer using a Mac computer
• Macs can’t communicate with motors, robots, sensors, etc without
something acting as a translator
• BreakTimer enables Mac to tell whether someone is sitting and if he/she
has been sitting for too long
• Real-time location systems
• GPS continually takes input data from satellite and stores longitude and
latitude
• Arduino Uno takes last received coordinates from GpsGate and sends
message to Google Earth
• Current location can then be shown on platform of choice
• Processing and image compression
• Arduino used as control element to integrate proposed algorithms
• Arduino enables further adjustments
