Multimeter/Oscilloscope/Sound Generator v2.0.1 (SAP) (Paid)

This Digital Multimeter 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 waves) 0Hz – 20000Hz included
9 – Color code resistance calculator
10 – Database for store data!
11 – Inductance meter!!

New functions:

1 – Ammeter!

2 – Capacitance meter 1nF-10000mF (High accuracy!)

3- Now you can save measuring data!!

10 – NO ADDS!

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 accuracy!

1 –
Check the voltage on the 5v pin of the arduino after connecting everything, because the voltage tends to fall a bit, normally drops to 4.8v so put an exact value in the arduino code, it is important because it is the reference voltage to measure ohms

2 – The values ​​of the resistances must be as accurate as possible

3 – You must weld all the connections to avoid parasitic resistances
