Here’s another interesting CheerLight project — a simple and effective RasPi + Arduino project that uses a ping pong ball as a collector and diffuser that permits a tremendously wide range of colors from the CheerLight feed.

The LED Node has been around for a while, but I wasn’t 100% happy with it. In principle, the LED Node v1 is a JeeNode plus 1.5 MOSFET Plugs plus an optional Room Board.

Temperature seems an obvious thing to measure, so a bit of rummaging disgorged a classic LM335 temperature sensor that produce an output voltage directly calibrated in Kelvin at 10 mV/K: room temperature runs 296 K = 2.96 V. Nothing could be easier than this:

A minimalistic single sided Arduino compatible development board that is easy to make. This is one of those many projects that I wish I could do with my students, but I would be the one having the joy of etching the boards due to safety.

Reading more than a few pushbuttons requires multiplexing, with a parallel-in shift register similar to the old 74LS166 being popular (and supported by the shiftIn() function). You can also use an Arduino analog input to multiplex the buttons, at the cost of a resistor string that probably draws more current and costs more than a logic IC:
