The Temperature Cubelet contains a tiny thermometer (actually, a thermistor) that detects temperature. It's calibrated to output a 0 in freezing conditions and 255 in hot, sunny conditions of about 35C. This Cubelet is pre-loaded with the newest Cubelets operating system, Cubelets OS 4.
The Threshold is a THINK Cubelet with a knob to alter the behavior of your robots. It will output a value of zero until its inputs exceed the threshold set by the knob. Above this threshold data will flow normally. Use this Cubelet to create robots that react suddenly, gate data flow, or exhibit binary behavior. This Cubelet is pre-loaded with the newest Cubelets operating system, Cubelets OS 4.
