If you can't find a voltmeter at home or anywhere else, then this hack is for you!
In this tutorial, I am going to show you how to build a voltmeter with a big Nokia 5110 LCD display using Arduino.
A 3V to 20V portable rechargeable power supply from off-the-shelf components. Powered by a single 18650 battery.
The Arduino input voltages can be easily monitored by using a standalone Windows application without Arduino IDE or the serial monitor.
A compact power meter. build to work with XT60 connectors
Voltmeter using arduino amd LCD display.
A simple, analog-style digital tester (voltage meter, DVM) created using the compact development module M5Stack.
Measure the juice left in your AA or AAA batteries anytime using an Arduino Uno and a couple of jumpers.
Frequency counter and voltmeter for Android phone or tablet using Arduino and Bluetooth.
This project is WiFi Oscilloscope with network volt meter arduino source code for esp8266 and esp32 WiFi modules + a nice web application
This is a small project which reads the voltage from power source and sends this data to cloud. Here the data is being sent to ThingsIO.AI.
Create a voltmeter using PCB and an ICL7107.
Measure the amount of energy or power or voltage left on your battery with couple of jumper wires and Arduino Uno.
This is the one, who can communicate and gives the reading of exact voltage by speaking. Powered by Arduino, make this more cool.
