Arduino LED Temperature Indicator
Above is a simuation. Click the "Start Simulation" button to begin. Click on the sensor labled "TMP" to change its value: the LEDs will light themselves according to the sensor's reading. This design is made to keep track of the temperature in a room. You give it the parameters you want and it will light a blue LED if it is too cold, a red LED if it's too hot, and a green one if it's just right.
