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
