Hi there.
I am looking for and LED meter driver which operates based on a 0 to 12 volt squarewave. I want the number of LEDs to light up to be proportional to the frequency of the square wave. Ideal would be 15 outputs, but need not be excact. I have been looking in some catalogues, but I have a bit of trouble deciphering all those codes and stuff. If anyone can help me with some of this it would be appreciated. (Should be available from Britain btw).
I will be able to use a frequency converter.
If it matters: It is to be used in a car, in british weather conditions, Not to hot or cold.
