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.

5. 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
@DocProfSky 5

6. Software Programming
• Sketch / Program: Three main parts
1. Structure
2. Values (variables, constants)
3. Functions
@DocProfSky 6

7. 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…
