About the Course

During the two weeks we will be together, our main objective is to learn the fundamentals of embedded programming on two processors: the Arduino and the Raspberry PiTo do this, our main project will be to build a working robot that can be controlled by various programs. We will use both the Arduino and the Pi for this.Embedded Programming and Robotics -- Introduction

2Slide3

About the Course

You’ll work in teams of 4. You can select your own team.This is a collaborative effort, not a graded class; you are encouraged to help each other learnBy the end of the workshop, each team will have a working robot and various programs for itWe will also do other small embedded-programming projects to illustrate principles

3Slide4

About the Course

We’ll be doing a little soldering, and we’ll use the multimeter when necessary to check out circuitsYou’ll learn basic Python programming and gain some familiarity with Linux if you don’t already have itAbove all, we’re here to have fun while we’re learningEmbedded Programming and Robotics -- Introduction

Logistics

We start at 9:30 every morning and finish the morning session at 12:30One hour break for lunchReturn at 1:30 and work until 4:30Breaks at 11:00 and 3:00 for about 10-15 minutesIf you need to take a restroom break other than the scheduled times, just goPlease wear your nametag

Workshop Format

This will be done as a workshop, not a regular classThis means that I’ll present for a while, never more than an hour at a time and usually lessAfter I have introduced a topic or defined a project, you will work on it in your groupOnce everyone has finished or come to a stopping point, we’ll discuss it as a class, then go on to the next topic

8Slide9

Workshop Format

If your group gets behind, try to catch up during lunch or after classIf I’m going to fast for the group, ask questions or ask me to give you more timeYou can take photos of things I present if you likeSlides and code will be made available on my Web site

9Slide10

What You Should Already Know

You should know how to program in C/C++ at some reasonably good levelYou should have a basic understanding of the components of a computer and how they work togetherAn understanding of basic electricity is helpful, but I’ll cover that

10Slide11

Secondary Skills

We will be doing a little soldering, but not much. If you want to make things more permanent, you can get circuit prototyping boards and solder components onto them.We will be doing a little mechanical assembly, but again, this will be pretty simple.You should document your work so you remember what you did. Often, we will build something, then take it apart and build something else. Photos are great, and so are written notes and diagrams.

Schedule Notes

There are some basic things we must cover, such as Arduino programming, Python, the basics of the boards, and so onHowever, if the class has a consensus on an additional related topic, or expansion on some of the existing ones, I’m open to suggestionsEmbedded Programming and Robotics -- Introduction

14Slide15

Murphy’s Law

Anything that can go wrong will go wrongCorollary: at the worst possible timeThis course involves wiring, electronic parts, and software you didn’t write. Things will go wrong. Connections will come loose, chips will burn out, programs won’t work the way you think they should, and so on. This is all part of our craft. Don’t worry about it.
