Hi all,

I'm new at this so some patience might be required, hopefully not
though

About to install a fluid level sensor in my car, it accepts between 5 and
12 V as input so I thought it'd be OK, good thing I realised that was
wrong before wiring it in

So... how do I make / get a cheap regulator to supply it's power? It's
current drain will be tiny. Is it worth using a 5V regulator given that I
have to use one at all? Presumably I'll need a small box and a breadboard
to solder various components into and stuff.

The output of the sensor is going to a piezo buzzer (max draw 10mA) then
to ground, it's a TTL output but I think that's OK.

TIA,

Peter.
