A sensor is a device that responds to a stimulus, such as heat,
light, or pressure. It then generates a signal that can be measured
or interpreted.
Humans, animals and even plants have sensors that can detect
the world around them.

Mini Arcade 8x8 LED Matrix
To load the code for the 8x8 LED Matrix, open a browser and select File !Open
and locate and select the file
dot-matrix-code-generator/dot-matrix-code-generator.html

/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.
This example code is in the public domain.
*/
// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;
// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
}
// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
Coding Tips
{ Curly Brackets }
Any code you write inside the
curly brackets will be executed
when the function is called.
// Comments
Comments are notes you leave
for yourself that the computer
ignores. To write a comment, add
two slashes // before you’re the
text you want ignored.
Case sensitivity
Pay attention to the case
sensitivity in your code.

Note: If the set-up is done ahead of
time, skip this step and proceed to the
next slide, Build the Circuit.
Step-by-step instructions for connecting
Galileo are found here:
https://software.intel.com/en-us/iot/
library/galileo-getting-started.
Within the step-by-step instructions,
when prompted to choose a
development environment, choose
Arduino.
Proceed all the way through the getting
started exercise to the point where you
blink the LED on the Galileo board.
This affirms the set-up was done
correctly.
Connect the Galileo Board and Install Software
Caution!
Always make sure the Galileo board is plugged in BEFORE
connecting the USB cable to the computer!
Also, always unplug the USB cable BEFORE disconnecting the
power from the Galileo.
Doing these steps in the wrong order can permanently damage
your board.

Note: If the set-up is done ahead of time, skip this step and proceed to the “Build
the Circuit” slide.
Instructions for Windows or Mac:
1. Download to the PC’s desktop the file called IESC.zip. (The file is attached to
the unit plan “Make a Mini-Arcade” housed in the Idea Showcase in
engage.intel.com.)
2. Unzip the file. This will unpack the zip file and place all the relevant files in a
folder called IESC it creates for you on the desktop.
3. Remember to tell your students that the sketches they will need to run for the
activities are located inside this IESC folder.

Wrap-Up Discussion
What did we learn?
Using the Intel® Galileo board
and the same set of sensors
and output devices, what
are some other types of
video games we could
create?
Can you think of any
interesting ideas for innovative
Interactive devices for the home?
How about ideas for wearable technology?
What kinds of careers are available to people who enjoy
this kind of activities?

Troubleshooting Guide
Problem Resolution
Sketch not working 1. Check Arduino IDE set to correct model, and Port
2. Check Galileo Port visible in device manager
3. Try resolution for port not visible
4. Try upgrading the firmware
1. Aurdino IDE Help -> Galileo Firmware Update
2. Click OK, if you have external power (This
step should take ~5 minutes)
Galileo port not visible in device manager 1. Unplug USB
2. Unplug and replug power
3. Replug USB
4. Wait
5. If not visable after 2.5 minutes, reboot PC and repeat
steps 1-4.
6. If still not visable check if Gadget Serial v2.4 is in
device manager
Gadget Serial v2.4 in device manager 1. Install Galileo Driver
Sketch upload complains about missing /dev/tty** Or
upload just hangs
Port may be locked, try steps under Galileo port not
visible.
Sketch upload complains about missing libraries 1. Close all arduino IDE instances
2. Install Grove libraries page 10
3. Restart arduino IDE
