does anybody know of something i can use to switch on and off a few LEDs at different amounts of resistance? im trying to make a rheostat bay bus and i thought it would be cool for it to have an LED (red) turn on at the first third turn of the rheostat, another LED (yellow) for the middle third, and finally another LED (green) for the last third turn. oh, and only having 1 LED on at a time. hopefully there is a simple IC or something that can do this....
