Im an F.E. Electronics engg. student. We have been given a Variable power supply project; i'm using an LM317 based circuit....

I want to know if there anything availabe which I can put on the box indicating the output voltage (e.g a small voltmeter ... like the one indicating the voltage on a stabilizer)? What do u call it?

You could use a voltmeter, a normal, moving coil analog voltmeter, or something like this (http://www.microchip.com/1000/pline/analog/anicateg/mixed/signal/dsplyadc/tc7_8xxx/tc7106a/) if you wanted a combined a to d with 7 segment out.
