Save a baby, nursery temperature monitor

Yes, you could argue this Nursery Room Temperature Monitor is simply an LED and an Arduino with a temperature sensor, but [Jay] really did put more thought into the process. For instance he stuck with AVR, built a wooden base and sanded globe, and even included schematics and source code. Plus, SIDS is no laughing matter and the more you know, the more it can be prevented. Back on point, one thing we would add is PWM for a more gradual change in color. What would you add?

Fritzing, go from prototype to product

fritzing

Fritzing is an open source project designed to help you move from a prototype to a finished project. Aimed at those basing their projects around Arduino, you start by building your physical prototype, then recreate it with Fritzing software’s graphical editor. From there you can generate a schematic, PCB artwork, and PCB production files.
