This Digital Multimeter 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 waves) 0Hz - 20000Hz included 9 - Color code resistance calculator 10 - Database for store data! 11 - Inductance meter!! New functions: 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. MY WEB PAGE : https://www.neco-desarrollo.es Please watch video tutorial How to use oscilloscope: https://youtu.be/ZwNe8yEjjxo **For build the circuit follow this** LINK FOR DOWNLOAD SCHEMATIC: http://neco-desarrollo.es/arduino-multimetro LINK FOR DOWNLOAD ARDUINO SKETCH HERE: http://neco-desarrollo.es/arduino-multimetro MY WEB PAGE: www.neco-desarrollo.es If you have any questions to mount the circuit or any other doubt please write us, the mail you can find below 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 Multimeter/Oscilloscope PRO try it now!
