Class Review + Bonus Material
Never forget Ohm's Law.

Arduino's language is based on Processing, another free, easy to use programming language. Download here. Go through tutorials here!
Every electronic component has a stat sheet. Here are links to the components I've made available to you:
The Arduino Uno.
Rotary Potentiometer. This was one of the first components you played with. Remember?
Relay. The one we used in class!
NTC Thermisters for measuring temperature.
Infrared Transmitters/Receivers. Links to store that includes datasheet for each, including a schematic and code for a completed project.
The PIR Motion Detector. Guess what it does!
Electret Microphone for detecting sound, accept no substitute.
Carbon Monoxide Detector for measuring the presence of this potentially lethal gas.
Barometric Pressure Sensor. If reading a thermister is like child's play to you, time to amp up your weather-sensing skills, and see if you can predict a storm before it happens!
PNP Transistors In case you want to play with more of your own switching circuits. You're probably going to use the Arduino for most of your logic, though.
Electrolytic Capacitors. These are a very useful component you see everywhere, and we have them in class. Just make sure to plug the long wire towards the greater positive charge, or these guys can and will blow up.
Infrared Emitters and Detectors!. And if you're trying to control a Nikon camera, you'd want to download some extra code from here.
Happy Holidays!
