HEC Arduino AVR Tutorial (updated March 17)

HEC is holding two events in March: the first is an Arduino group buy/assembly session on Thursday March 27, 2008 at 10:00 AM in ENG303 and the second is an Arduino/Atmel AVR tutorial on Friday March 28 at 3:00 PM in ENG408.

  • The assembly session and group buy is where you can purchase an Arduino if you don’t already have one. They come in kits that require some soldering. Experienced HEC members will be on hand for assistance. This is the March 27 event in ENG303.
  • The tutorial is a two hour seminar on March 28 in ENG408 where we will be teaching/presenting/demonstrating how to use your new microcontroller. All you need is a basic understanding of C and similarly basic electronics experience. The goal is to come out of the seminar with basic experience on the Arduino platform and with the ability to read from the PS2 controller so you can use it for your own projects.
  • This event is open to all Ryerson students.
  • The cost will be $40 and you get to keep the microcontroller and kit.

Frequently Asked Questions

What can I do with it?

It’s a full-fledged microcontroller. You can program robots, automate things, make lights flash, make a really crappy digital synthesizer… See next question for limitations.

How powerful is it?

It’s about as powerful as a PIC and in the same class as the 68HC11. However, unlike the HC11, it’s a new design and so benefits from modern CMOS process. For the geeky details, see this page

Why not the PIC?

For a comparison of the two, see this page. I just happen to prefer the AVRs over PICs.

What do I get?

You get the microcontroller board, a special serial cable, a PS2 controller adapter and maybe a couple of other fun things necessary for the session. Here is a pic of the micro and PS2 adapter.

AVR PS2 Code

Since it’s been asked for a number of times, the code is hosted on nokturnal here.

This Week in HEC #3

This week,
1. Kevin & Mauro put together an h-bridge based on Chuck’s Robotics design

2. We assembled a cheap Arduino clone called boarduino. It fits in a normal breadboard and looks like this:

3. We partly disassembled the e-savage in preparation for repairs.
4. John put the PS2 controller code together with the rc tank code and […]

Week in Review

This week,
1. We field tested the newly acquired RC monster truck. It was really damn fun taking it off ramps. It took one too many at an odd angle: we busted a piece of plastic and bent part of the chassis. Turns out impacts with cement floors aren’t so good for rc cars…

2. […]

This Week in HEC

We’re back for 2008. Meetings are still on Wednesdays at 6:00 PM in ENG 303. Any interest in an additional meeting time?
This week:
- Wireless PS2 Controllers: we interfaced with a wireless controller (a Pelican Chameleon) from Arduino! The range was about half the length of the engineering building with increasingly laggy responsiveness.  […]
