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!
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
