The indicator moves up from zero to 5V as they play the right notes, and it drops to zero when they make a mistake. Very cool, with the needle jumping to (and overshooting) each new position, and it really helps the kids solve the puzzle.<p><a href="https://www.youtube.com/watch?v=Ty5BYRizWHo" rel="nofollow">Project Video</a></p></p>

The MC33269D-5.0 voltage regulator on the UNO can drop up to 1.35v off whatever you power it with, which could explain the 3/4 deflection. But you've had success since? I'm considering purchasing one of these to use with analogWrite().</p>

You can <a href="http://web.archive.org/web/20120130022305/http://www.circuithowto.com/2011/01/scale-template-for-sfes-analog-power.html" rel="nofollow">read the post through the wayback/internet archive</a>.<p>The PDF linked to the in the article never worked, but the PING and GIMP file links work; just remember to remove the archive.org bit from the link and go straight to the dropbox location. They are fairly low resolution, so if you want to print your own you may wish to scale the image up first and draw on that, using the outlines only as a guide :)</p></p>

Not only does it NOT have a zero adjust, but the full scale deflection was over 6 volts for me. I Had to not only open it up to manually twist the assembly so that the needle pointed to zero, I had to change the resistor so that the meter was actually 5V full scale. I'm very disappointed that Sparkfun would sell such a low quality item.</p>

I think you need a little glue too for the top of the plastic cover as when you take it off the glue breaks(which I didn't realize until I'd taken it off).<br>
Anyway Hope this helps :P</p>

The meter movement needs about 230mV for full scale deflection (fsd). The 5V version has a 5k series resistor to give fsd at about 1mA. You can adapt them for any fsd voltage above 1/4 Volt by changing the internal series resistor. A multi turn trim-pot is the easiest way to get it right. 10k will give you up to about 10V, 20k for 20V etc.<br>
For an ammeter it's a bit harder as you need a shunt resistor across the terminals to carry most of the current. Calculate the resistance to give 250mV across it at the current you want as fsd then add a low series resistor inside the meter to bring the fsd back to the correct point.<br>
I made a replacement 5A meter for my battery charger with a 0.05 Ohm shunt (two 0.1Ohm power resistors in parallel) and needed a 10 Ohm series resistor to get the correct reading.<br>
Works a treat.</p>

That would place it at about 0.72mA for full scale displacement. There is an internal resistor that you could change if you wanted different scale. I didn't look at its value.<br>
Just a note, one of the two I purchased didn't work. Opening the meter, the wire connected from the stud on the back to the movement had fallen off. I just resoldered it and it works fine. It is easy to disassemble these meters to change the scales or resistors.<br>

There appears to be a line molded onto the back next to a screw, which might be a -, but there's no +.<br>
Is it just the two upper screws on the back?</p>

I've been looking for little meters, they've gotten hard to find! LEDs are great, but nothing beats the swinging needle for that dynamic pulse. The 5V meter is just right to drive with an Arduino PWM pin, using analogWrite(). Looks like it can be opened up to put in a custom laser-printed scale. (Who will post a template?) We do need to know the sensitivity in ohms per volt. Thanks!</p>
