Mar 02, 2011 · I was looking for a real device project to get out from "blinking leds" of Arduino's tutorials and build a device that could be useful in some way. I always thought confuse to have to use two voltmeters, besides the excess of wires around, I already burnt almost all current scales from my voltmeters, to measure current and voltage simultaneously. For the Analog meter, it just needs a ground connection, and a PWM connection (I'm using PIN 11) with a 100k ohm resistor. Here's the Arduino Code - I know it needs some commenting and cleanup. This has a much cleaner input method via serial than the last version!
Jul 17, 2012 · The sensor range output voltage is 0.5-4.5V, if use a 5V as reference for the analog readings, then 5V = 1024, 0.5V = 102 and 4.5V = 922 . For better results check the VCC voltage of the Arduino and adjust.
