CO2 sensor used with Arduino
if you go to rswww.com and search for part number 538-9897 you will find the Figaro CDM4161 - that is the device shown in the image.
We use the mood information from the music to light up the background of the large monitors. The large monitors mirror what is going on the car stereo head unit. All the parts are from Adafruit. The car stereo uses usb/serial to communicate with the arduino. See flic.kr/p/pTpt9k for details

This is the CTCSS generator opened up.
The Arduino is fastened to the lid, thumbwheel switches, 5 volt regulator, and 4018 sine converter are fastened to the bottom. 10k trimpot to adjust the tone level.

This is a full shot of the robot while lying down.
This project uses an Arduino to drive a miniature "segway" balancing robot.
A pair of Lego Mindstorm NXT motors are used to drive the robot wheels. An Arduino is used to control the motors. An ADXL335 3-axis accelerometer is used to determine robot orientation. An L293D H-Bridge is used to allow the Arduino to interface with the Lego NXT motors using pulse-width modulation signals. A proportional-integral-derivative (PID) algorithm was used to determine the logic for wheel movement. Programmed in C++.
Unfortunately, the robot required "human assistance" to stand up on its own for any length of time. I wish I had a bit more time on this project to continue tweaking the PID algorithm to improve this.

No server required.... Arduino + LadyAda ethernet shield with Wiznet module, plus external power supply. The blue ethernet cable's plugged directly into my broadband router.
The lego stand for the current cost allows the black cable in the bottom.
This is now logging my electricity consumption to pachube.com!

Wanting to participate in the Cheerlights project (www.cheerlights.com) but not having the dough for a full string of Christmas tree lights ($70), I whipped up a small tree out of a sheet of expanded PVC board, painted it appropriately, and mounted ten RGB LEDs on it. The Arduino microcontroller inside the box uses it's Ethernet Shield to communicate directly with the Cheerlights ThingSpeak Channel over the internet. The Arduino changes the color of the lights (along with all the other Cheerlights projects in the world) every time a new color is Tweeted by anyone with a public Twitter account. The box does not attach to a computer, it plugs right into our home network. More comments and a link to my Arduino code can be found at makeprojects.com/Project/Cheerlights-Desktop-Christmas-Tr...
I just finished my Breadboard Arduino, I programmed the chip with the blink example using a reugular Arduino.

So, this is the Arduino mood cue thing from the top. You wire up a potentiometer to a servo motor which then swivels the arm around. I'm getting a little bored of just wiring up and coding the things in the book so I decided to build on it and make something of my own.
Our third Arduino 101 class at Tam Makers went really well. I taught this evening course with co-instructor Donald Day on Thursdays, from June 16 to 30, 2016, at the woodshop in Tam High School in Mill Valley.
We worked with an enthusiastic group of seven students, including adults with diverse backgrounds, as well as a couple high school students. Our partner Geo Monley worked both as a mentor and as a student during the hands-on sessions.
We started the class at 6pm, by giving students an overview of how circuits work. We then learned how to use a multimeter, how to solder electronics, and how to control rainbow-colored NeoPixel lights.
Students seemed to really enjoy this class and told us they learned a lot from it. Several expressed an interest in taking intermediate and advanced classes in the future. This is one of our first maker courses at Tam Makers, and we’re really happy that it is going so well; we look forward to teaching more classes in the fall.

We taught a workshop on how to create interactive art with the Arduino platform at the Mill Valley Library on October 24, 2015.
We showed 9 students how to make lights blink, sounds play, motors move, and how to add more color with neopixel LEDs, as described in this online guide we created for the workshop:
At the end of the workshop, we asked participants if they would like to this again, and the answer was a resounding yes! Participants told us they learned a lot from this workshop and would not only come back for future workshops, but also recommend this program to their friends.
Instructors for this workshop were Donald Day and Fabrice Florin, with support from Natalie and Jean Bolte. We are all members of Pataphysical Studios, the art collective behind the ‘Pataphysical Slot Machine’, our poetic oracle.
Come visit the exhibit this month! We’re open every Saturday and Sunday in October, from 1 to 5pm, in the downstairs conference room of the Mill Valley Library.
Special thanks to the Mill Valley Library and the Friends of the Library for making these workshops possible — especially Kristen Clarke, who helped us get the Arduino parts and set up for the workshop.

It is quite spooky when your arduino starts acting all paranormal after midnight.
Why would i turn on the red LED when i reach for the knife ?
It was after i was halfway dismanteling a test setup with a photocell when i discoverd this behaviour by accident.
There will be a perfectly scientific explenation to all of this.
But still :)
int h5=0;
void setup() // run once, when the sketch starts
{
pinMode(11, OUTPUT); // sets the digital pin as output
Serial.begin(9600);
}
void loop() // run over and over again
{
h5 = analogRead(0); // read the value from the sensor
if (h5>100)
{
digitalWrite(11,HIGH);
}
else
{
digitalWrite(11,LOW);
}
// analogWrite(11,h5);
// Serial.print(h5);
// delay(500);
}
