Arduino Digital Multimeter Lt is Digital multimeter (DMM) app using Arduino. You need not any bluetooth module and any supply power.
You need just one Arduino Board(UNO, MEGA, anything else), cables(USB, USB-OTG, probe cable) and Android Smartphone with USB-OTG.
(Recent Android Smartphone has almost this USB-OTG function.)
You can measure the voltage(-50 ~ 50 V) and resistor value (1 ~ 500 kohm or more) like usual DMM. (I recommend Calibration function must be done before 50 V mode for more precise measure.)
It's usage is very simple.
Download below code to your Arduino and connect wire to A3 and GND.
That's all. You can measure the voltage with your Android phone.
========================================
int value, i;
void setup() {
Serial.begin(115200);
}
void loop() {
value = 0;
for (i=0;i<10;i++)
value += analogRead(A3);
value /= 10;
Serial.write( "Start");
Serial.flush();
Serial.write( (value >> 8) & 0x03);
Serial.write( value & 0xff);
}
========================================
Connection for other modes (50V, resistor, short) can be informed at inner blue button.
For more detail Quick Start, you can visit at "http://blog.daum.net/jedi_jaja/2".
For the other usage (50V, Resister, short, Calib, Save ), you can see at

Don't be afraid. It's very Simple. And "Quick Start" in app setting button. you can enter above site directly.
Enjoy this app.
