Photo cell (CdS photoresistor)

Product ID: 161

CdS cells are little light sensors. As the squiggly face is exposed to more light, the resistance goes down. When it's light, the resistance is about ~1KΩ, when dark it goes up to ~10KΩ. To use, connect one side of the photocell (either one, it's symmetric) to power (for example 5V) and the other side to your microcontroller's analog input pin. Then...

L3GD20H Triple-Axis Gyro Breakout Board - L3GD20/L3G4200 Upgrade - L3GD20H

Product ID: 1032

A gyroscope is a type of sensor that can sense twisting and turning motions. Often paired with an accelerometer, you can use these to do 3D motion capture and inertial measurement (that is - you can tell how an object is moving!) As these sensors become more popular and easier to manufacture, the prices for them have dropped to the point where you can easily afford a...

Flat Vibration Switch with Breadboard friendly pins

Flat Vibration Switch - Breadboard friendly

Product ID: 4081

This is a low sensitivity, directional vibration-induced trigger switch. Inside is a very soft spring coiled around a long metal pin. When the switch is bumped from the side only, the spring attached to the first pin touches the center pole to make contact with the second pin. So when there's a bump, the two pins will act like a closed switch. When everything is...
