description
This 60 minute course covers the basics of Arduino. It spans from an overview of the board design (components, I/O, power, etc.) to the software development environment. Schuyler St. Leger (a.k.a. @DocProfSky), the instructor, then goes through several live examples of prototyping circuits using an Adruino Uno and a breadboard along with additional components. You will need to watch the full 60 minute video is on Youtube to see the programming examples. Programming and circuit examples include: 1) Blinking the on-board LED. 2) Blinking an LED via the digital header I/O. 3) Adding a button switch into the circuit to control the LED's on/off/on modes. This circuit expansion introduces a breadboard and the concept of a pull-down resistor to suppress electrical noise. 4) Using a potentiometer to control an LED's blink rate. The inner workings of a potentiometer is also explained. 5) Using a potentiometer to control an LED's brightness using Pulse Width Modulation (PWM.) The concept of PWM is also explained. 6) Controlling a servo motor. 7) Using a potentiometer to control a servo motor. This course was presented at Desert Code Camp, November 2012 at Chandler-Gilbert Community College in Chandler, AZ.

Agenda
• Overview of Arduino
• Software overview
• Live examples of programming
• Some references for further enlightenment
3 @DocProfSky
What is Arduino?
• Open-source electronics prototyping platform
• Hardware based on Atmel 8-bit microcontroller ATmega8 series
– The DUE is 32-bit
• Open-source hardware
• Open-source software
4
Arduino Uno: What’s What
USB Port
Clock/ Oscillator
Micro-controller
DC Power Port
Power Regulator
Reset Switch
Header for Digital I/O
Analog Input Header
LED Pin 13
USB Inter-face Chip
Power Header
5 @DocProfSky
Software Programming
• Integrated Development Environment (IDE)
– All-in-one programming tool with built in compiler
– Supported host development platforms • Microsoft Windows
• Mac OS X
• Linux
• Arduino language is C/java based
6 @DocProfSky
Software Programming
• Sketch / Program: Three main parts
1. Structure
2. Values (variables, constants)
3. Functions
7 @DocProfSky
Software Programming
Let’s see some examples (easier to harder):
• Basic sketch to blink an LED (“HELLO WORLD”)
• Using a push-button switch to control an LED
• Using a potentiometer to control an LED’s blink rate
• Using a potentiometer to control an LED’s brightness (using PWM = Pulse Width Modulation)
• And more if we have time…
