Arduino 101 by Schuyler St. Leger - Desert Code Camp - 2012 Nov 17


Published on

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.
