Hi Guys & Girls,
1st post so go easy on me.
Im wanting to make a LED level indicator, so once I press a button it shows me how much water is in a tank.
The power supply needs to be 12v.
I was thinking of taking a straight 12v+ feed from the supply and placing that at the bottom of the tank with a button halfway along the wire. I would then solder 10 leds along the same 12v+ feed, then cut different lengths of wire and attatch them to the - side of the leds. When the button is pressed then the circuit is made and the relevent leds light up.
Im sure I'll probably need resistors and what not so thats why I'm here so someone can hopefully point me in the right direction.
Thanks
Nathan
