Right, i think this is exactly what i need, so thanks very much fried.
Did you personally make this circuit? If no, would you be able to help me abit?
I have been doing some electronics but not alot. I can figure out the basics of the circuit, ie what position the resistors/capicitors go. But will need some help figuring out what pin of the chip connects to each, but i can reasearch the majority of that myself.
One thing i ask is on the 12v measure would i be correct in saying that this circuit has NO extra power source? And is driven directly off of the battery that you connect it to?
And last at the bottom where it says
Adjust R3 for 3.6v at pin 6
Adjust R2 for 2.4v at pin 5
Adjust R5 for LED 4 on with 12v input
Is there any way that i can do this? I just assumed that you have already used the correct resistors, or are they just approximates? And i would need to 'fine tune' the circuit by using another voltmeter to increase the accuracy of it?
But thanks very very much for your help, i am very grateful for it!

P.S Looking at the parts to order and im debating what type of capacitor that is? And i'm also abit unsure of what value it is, 0.1uF ? Is what i can see?
