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. Find this and other hardware projects on Hackster.io.
Voltmeter Clock: This clock tells the time - hours, mins, and seconds using 3 analogue voltmeters. A PIC16F628A microcontroller is used to display the time by varying the voltage to each voltmeter and also provides very basic timekeeping. The Microcontroller code is…

6 Channel Voltmeter: Some special applications often have to measure the voltage from several parts at the same time for example electronics repair, scientific and experimental purposes. if you're building a battery pack it can also show the voltage of each cell simulta…
Regardless of whether you're a professional electrician, a DIYer, or somewhere in between, a multimeter is capable of keeping all of your electrical projects simpler, more secure, and more productive. These are the best digital voltmeter & multimeter in the market.
This is a project based on Arduino board which can measure the unknown AC and DC voltages. When we connect the unknown voltage on the breadboard circuit, the 16x2 LCD displays the voltage value. The project uses an Arduino pro mini board whose ADC feature is used along with the concept of Voltage Divider circuit to develop this Voltmeter.

Introduction This project describes how to make a digital voltmeter using a PIC microcontroller. A HD44780 based character LCD is used to display the measured voltage. The PIC microcontroller used in this project is PIC16F688 that has 12 I/O pins out of which 8 can serve as analog input channels for the in-built 10-bit ADC.Read More
I wanted a digital AC voltmeter to measure the output range from 0 to 150VAC with reasonable accuracy. Sure I could buy some premade DVM packages or use a microcontroller with a built-in ADC, but I wanted to make one from scratch myself using readily available parts I had on hand. I aimed for reasonable accuracy so I chose to have a 2 and a half display for the voltage, meaning the meter reads from 000 to 199. Below is the schematic of the AC DVM.
