Danger Shield
The Danger Shield mounts on top of your Arduino or Arduino Pro and equips it with a variety of fun and useful inputs and outputs. The Danger Shield has so much potential; we can't wait to see what you're able to do with it!The shield's features include:Three linear slide potentiometers connected to the Arduino's analog pins 0 through 2.Red and yellow LEDs connected to digital pins 5 and 6 - PWM pins - so you can easily vary their brightness.Three momentary push buttons connected up to the Arduino's digital pins 10 through 12. Those lines will go low when the buttons are pressed.A photocell and a temperature sensor, both with analog outputs, are connected to the analog pins 3 and 4, respectively.An 8-bit shift register set up to control a blue 7-segment LED.Two buzzers - one is used, as you'd expect, as a speaker, the other is connected to analog pin 5 and can be used as a knock sensor.This new version uses a different temperature sensor. This product comes as a kit of parts, which you'll have to solder into the included PCB. All parts are through-hole so it should go together relatively easily; but always check your component orientation before soldering!
