Pi Camp

Day 1

Purpose Day 1

Get to know each other
Hook up and secure your Pi
Learn a bit about the GUI and the Command Line
Learn the basics of the Pi Machine
Look at where we are going
Build a basic circuit

Ice breaker

Who are you
Why are you here
What do you want to learn

Set up the Pi

Add heat sinks
Install the Case - Your case will most likely be different from the one shown
Insert the SD Card.
Connect the keyboard, mouse and video

Keyboard and mouse will be via keyboard dongle.
video will be through the HDMI port.

Power on. You should see something like:

Without the mushrooms. Those are Deid's
What are the buttons (icons)? Describe them.

Change the password and remember it.

Terminal session
passwd command

Some useful Linux terminal session commands

man - show manual for a command

cd - change directory
pwd - print working directory
passwd - change password

Pi Overview - What is in your kit.

Pi
Prototype Board
Smoke - more later
Turning the Pi Off - need to shut it down safely.

Have the students turn a light on and off on My Pi. http://<ipaddr>/onoff.html (need to get this ip address) e.g. http://192.168.0.123/onoff.html

This is "equivalent" to hello world when testing hardware ...

Demo of an on off circuit.
Replace this with Eileen's
A bit about LEDs and resistors.

Wire on off circuit with 9 V battery, (switch?), LED and ~470Ω resistor. Remember + and - for the LED

Lets have some red and black tape to mark polarity if needed.

Questions:

Which lead is the positive lead in an LED?
Does the position of the resistor matter?
