Hey guys I need some help in implementing this idea. The idea is that I want RGB led to show 3 colours at different range of temperature. For example when temperature is 40-50 = RED, 30-40 = Yellow and 20-30 = green. I'm using LM35 temperature sensor to read the temperature. I have already coded to read the temperature and now want to know how to turn RGB LED in different colours at different temperature.
By, the way did anyone come up with a sample code to do something like this in arduino playground other than http://www.insanegiantrobots.com/arduino/rgbled.html
