Hi,
I am working on my first 3914 circuit to construct a fuel-gauge. I have done my calculations based on datasheets and on other peoples projects and I thought everything should run smoothly but I had some strange results.
I've searched the forums for answers to my questions to no avail.
Can you tell me which voltages this setup is supposed to measure? How many volts to light 1st LED and how many volts to light 10th LED? And how many mWs should each LED be getting?
I'm curious to see if my calculations are correct but just doesn't work or if the circuit is doing what it should and the fault lies with me.
Help and answers are greatly appreciated!
Edit: I'll post my actual readings on the circuit after someone can say what it SHOULD read.
