Hello to every 1 that actualy bothered to read this msg.
I am a NOOB at electronic circuit building. The only project I ever accomplished was building a simple fan controller using a few rheostats and LED's. I have no experience with CHIPS. I heard quite a bit of information about the LM3914 CHIP, and now I want to build a fan controller for my computer using the old rheostats and this MAGIC CHIP. I want to use a 10 segment LED block but I have no idea how to hook it up. The input Voltage to the rheostat is 12V. The output voltage obviously going to vary depending on the position of the shaft of the rheostat and the load. I just want to build a small circuit that will light up more LED's as the voltage goes up and will extinguish LED's as the voltage drops when I turn the shaft on the rheostat. As I mentioned earlier, I do not have much experience and I don't know were to look for answers except this place that looks very attractive to me .
Any suggestions would be appreciated with great prosperity regardless of their nature.
Thanks,
Andrew (Just another noob entering the highly sophisticated world of electronics)
