Hello all, im new to electronics, so dont know the full lingo, its just a hobby for me.

Ive seen a low fuel indicator i would like to make.

From whot i can gather it should tell me, my fuel is down to 5 litres.

The parts listed are?

Semiconductors;
LM311N comparator.
78L10 voltage regulator.
4.3v 500mW zener diode.
LED (any color)

Resistors;
22k 0.25w
4.7k 0.25w
1.8k 0.25w

Capacitors;
1000uF 10v
100uF 16v
47nF 63v

I be greatful if someone could point me in the right direction.

Im not to good on reading schemacics.

I try an post some links to were i seen it.

I going to the shops before they close @4pm getting myself a rotary set.

Thank you if you can help me Im not sure if the schematic an the imaged shown or the same.

Sorry about the large image 1st time ive done this?

Can you point us at a link for the circuit? There really do not seem to be enough parts listed to make a fuel level sensor.

 

pls post a direct schematic(either in form of jpg or any other supported format within this web site.AAC) so that we can be able to help you.
Thanx

 

Hope this helps

Do you know how the comparator works, would you like to know? I'd be happy to explain it.
This page was great when I was first learning to use a comparator.
