Digital Multimeter

ڈیجیٹل ملٹی میٹر وولٹ میٹر، ایممیٹر اور اوہم میٹر کا مرکب ہے۔

Multimeters are the Digital Multimeter size equipment which assist you to degree fundamental electric portions consisting of voltage, present day and resistance. In different words, a Digital Multimeter is a mixture of the voltmeter, ammeter and ohmmeter. Modern virtual Digital Multimeter are loaded with more than one capabilities consisting of capacitance size, temperature size, continuity tests, transistor running, battery testing, and diode checking. Keeping a lot of these factors and electric enterprise in view this Digital Multimeter app is designed to offer you the statistics approximately running of the meter. After going via this Digital Multimeter software you may find out about the fundamental idea of Digital Multimeter in addition to you may be capable of use your tool for appearing specific calculations.

Arduino Digital Multimeter Lt is Digital Multimeter (DMM) app the usage of Arduino. You want now no longer any bluetooth module and any deliver power.

You want simply one Arduino Board(UNO, MEGA, whatever else), cables(USB, USB-OTG, probe cable) and Android Smartphone with USB-OTG.

(Recent Android Smartphone has nearly this USB-OTG characteristic.)

You can degree the voltage(-50 ~ 50 V) and resistor value (1 ~ 500 kohm or extra) like standard DMM Digital Multimeter . (I suggest Calibration characteristic need to be achieved earlier than 50 V mode for extra particular degree.)

It's utilization may be very simple Digital Multimeter .

Download beneath code in your Arduino and join twine to A3 and GND.

That's all. You can degree the voltage together along with your Android phone.
