A REST API for Arduino & the CC3000 WiFi Chip
Stop reinventing the wheel and control your Arduino board using RESTful calls!
Representational state transfer (REST) is a software architecture that is widely used for web applications. In this project, we'll bring this architecture to Arduino so you can control an Arduino board via WiFi using a standard communication scheme. This way, you won't have to start from scratch at every new project and you'll be able to create complex wireless applications!

Adafruit 1-Wire GPIO Breakout - DS2413
Running out of pins on your Arduino?
Pins are precious in the microcontroller world. How many times have you needed just one more pin? Sure, you could step up to a Mega and get a bunch more, but you really just need one or two. The DS2413 breakout board is the perfect solution. Each DS2413 breakout has 2 open drain GPIO pins and a 1-Wire interface. Just one of these boards will give you 2 pins for the price of one. But you can keep expanding from there. You can put as many of these boards as you want on the the 1-wire bus and still control all of them with just one Arduino pin. Each chip has a 48-bit unique address, which means you could have as many as 562 trillion GPIO pins! (In theory anyway)

Adafruit SI1145 Breakout Board - UV / IR / Visible Sensor
A tutorial to help you get started with the SI1145 light sensor
The SI1145 is a new sensor from SiLabs with a calibrated UV sensing element that can calculate UV Index. Unlike a basic UV analog sensor, it has a weighted calibration for UVA, UVB and UVC to give you a more precise UV index output than just "mW/cm2". It's a digital sensor that works over I2C so just about any microcontroller can use it. The sensor also has visible and IR sensing elements so you can measure just about any kind of light
