萬用表/ 示波器

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 - 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.
