Circuit diagram of the DC panel meter using Arduino is shown in Fig. We also display the voltage reading on an LCD 162 Display. Toggle Nav. DC is more dangerous than AC for the same voltage as it is significantly harder to switch off (standard AC mains fuses will not work reliably on DC for instance). It works fine, though the readings gathered are noisy. 1. I was thinking of using a voltage divider with four series resistors (in case one fuses). To scale the numbers between 0.0 and 5.0, divide 5.0 by 1023.0 and multiply that by sensorValue : float voltage= sensorValue * (5.0 / 1023.0); To measure DC input voltages very precisely using Arduino. I haven't sketched out this circuit yet because I'm still looking for a different approach. Then you can connect the sensor to your Arduino - and measure again to make sure you see the same 2.25V on your analog pin (use the one you have set in your software). As you may well know, Arduino's analog inputs can be used to measure DC voltage between 0 and 5V (when using the standard 5V analog reference voltage) and this range can be increased by using two resistors to create a voltage divider. 17.507 SYP.
