This is one of my favorite products - the danger shield
- mostly for the potential I can see in customers' future projects! This shield mounts on top of your Arduino
or Arduino Pro
and equips it with a host of useful inputs and outputs. I feel like Q
would give James Bond one of these to tinker with. The inputs and outputs include the following: three linear slide potentiometers, red and yellow LEDs, three momentary push buttons, a photocell and a temperature sensor, an 8-bit shift register set up to control a blue 7-segment LED, and two buzzers - one is used as a speaker, the other is
connected to analog pin 5 and can be used as a knock sensor. This comes as a kit that you have to solder, but all components are through-hole!
This is a simple breakout board
for Analog Device's AD5330 8-bit
digital-to-analog converter (DAC). The AD5330 has a parallel interface,
and can operate from a 2.5 to 5.5V supply consuming just 115uA (at 3V).
This is a lens
designed to fit three ultra-bright Luxeon Rebel LEDs
. The lens is 50mm in
diameter and has a smooth surface to produce a narrow beam with a 10?
angle. This lens will create a relatively focused beam. Perfect for your homemade flashlight or headlamp!
This is another lens
designed for use with the Luxeon Rebel LEDs
. While the previously mentioned lens is a narrow beam, this beam diffuses the LEDs to create a wide beam of light!
Happy Friday everyone - cheers!
