I am trying to make a digital fuel guage using a lm3914 a 5v dc to dc chip but i am afraid after years of not working with electronics i am stumped i cant even get this chip to light up the bar graph the sender unit in tank is basically just a variable resistor so if i just put a pot inline i can prob use that to calibrate a bit. if anyone has worked with this chip and can give me a good mostly complete diagram of what i am going to need i would love it this is takeing me forever to figure out.
