Just finished the work on my multimeter-box using an esp32 and an ina219 voltage and current sensor.
With the box, you can measure voltage and current at the same time.
The links show a few examples of the charge and discharge of a capacitor and the characteristics of a diode and a resistor.
The Arduino code and the 3dp files can be found on Github. The building instructions will follow.
