Hello. I am working on a simple circuit for determining the voltage output from a small hand-made windmill generator. The circuit uses an LM339 quad comparator to light up 1-4 LED's depending on how high the voltage from the generator is. But for some reason, the LED's are either all on or all off. Could someone look at the circuit and help me figure out what's wrong?
Before everyone goes crazy about you doing my homework, I would like to point out that the assignment does not require me to do this at all. I just thought it would be cool if I could get it to do this. The assignment was merely to build a windmill to light up a small (1.5V) incandescent light bulb, which our windmill blew out long ago because we get a max of 16V out of the thing. I am reasonably new to circuits (I have not been through any ECE classes yet), and would like to understand what it going wrong here.
Thanks in advance for your help.
