About this app

This Digital Multimeter/Oscilloscope help you to
measure:

1 - Volts
2 - Ohms
3 - Temperature
4 - The light (lx)
5 - Frequency
6 - Amplitude
7 - Oscilloscope included
8 - Sound Generator sine/square wave 0Hz - 20000Hz included(in version pro)
9 - Color code resistance calculator
10 - Save measuring data!!
11 - Added capacitance meter from 1nF to 10000 mF
12 - Inductance meter!

It's easy to build, you just need:

1 -A arduino uno or nano
2 - Bluetooth module(HC-05 or HC-06)
3 - Temperature sensor(TMP36)
4 - Some resistances.

And for Oscilloscope:

1 - A old headphones with 4 pins
2 - Capacitor from 0.1mF to 1mF.

Councils to improve the precision:

1 - Check the voltage of 5v pin of arduino after connecting everything, it is the reference voltage to measure ohms when connecting the bluetooth module the voltage drops a bit, it can be in 4.8v, put exact value in the arduino code

2 - The values ​​of the resistances must be precise

2 - You must weld all the connections to avoid parasitic resistances

Ratings and reviews

Five stars inertial rating in trust that I will be informed as to how to operate it, how to connect it ect. The opened app prompts me click the link below for operations instructions,,,. Um, but, ahh well there is NO LINK BELOW to click, no instructs and no directions to inform me pertaining to "How-to-Connect,,,. Remediation for header message that states, "Not Connected ". In actuality, Not Informed. Please help.

As an Applied Physcist-Electronics Engineer on the go. This app is 110% functional as a dmm, or oscilloscope. The ads can be removed if you actually buy it. And even those are not as bad as someone below states. The developer could easily just make this a complete app without the arduino addons, take a usb / USB-c cable, and connect leads to it.

AD restrictions for usage ! Good idea, bad implementation..... Sad to see monetization in this way, ruining a perfectly good application i would be happy to pay for. AD versions of apps take away from the quality and experience. I had to do some digging to find the paid app, which I will purchase, and give 5 stars.
