Multimeter/Oscilloscope Pro

Features Multimeter/Oscilloscope Pro

This Digital Multimeter help you to measure: 1 - Volts2 - Ohms3 - Temperature4 - The light (lx)5 - Frequency6 - Amplitude7 - Oscilloscope included8 - Sound Generator (sine / square waves) 0Hz - 20000Hz included9 - Color code resistance calculator10 - 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!Its easy to build, you just need: 1 -A arduino uno or nano2 - Bluetooth module(HC-05 or HC-06)3 - Temperature sensor(TMP36) 4 - Some resistances.
And for Oscilloscope:1 - A old headphones with 4 pins2 - Capacitor from 0.1mF to 1mF.MY WEB PAGE : https://www.neco-desarrollo.esPlease 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-multimetroLINK FOR DOWNLOAD ARDUINO SKETCH HERE:http://neco-desarrollo.es/arduino-multimetroMY WEB PAGE:www.neco-desarrollo.esIf you have any questions to mount the circuit or any other doubt please write us, the mail you can find belowCouncils 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 ohms2 - The values ​​of the resistances must be as accurate as possible3 - You must weld all the connections to avoid parasitic resistancesMultimeter/Oscilloscope PRO try it now!
