This Digital Multimeter/Oscilloscope help you to measure: 1 -Volts2 - Ohms 3 - Temperature 4 - The light (lx) 5 - Frequency 6-Amplitude 7 - Oscilloscope included 8 - Sound Generatorsine/squarewave 0Hz - 20000Hz included(in version pro) 9 - Colorcoderesistance calculator 10 - Save measuring data!! 11 -Addedcapacitance meter from 1nF to 10000 mF 12 - Inductance meter!It'seasy 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 with4pins 2 - Capacitor from 0.1mF to 1mF.
