How to make an Arduino Voltmeter. As you may well know, Arduino’s analog inputs can be used to measure DC voltage between 0 and 5V (when using the standard 5V analog reference voltage) and this range ...

Connection for this Arduino Digital Voltmeter is simple and shown in the circuit diagram below: Pin DB4, DB5, DB6, DB7, RS and EN of LCD are directly conneted to Pin D4, D5, D6, D7, D8, D9 of Arduino ...

Voltmeters aren’t terribly expensive, but it’s always more fun to build your own devices. YouTube DIYer Educ8s builds a cheap voltmeter for less than $10 using an Arduino and a voltage sensor ...

A few months past and I gained some interest in making this OLED work. Therefore, I started to do some research. I found a library that supports all sorts of displays for Arduino, and it supports ...

On the receiver side, there’s an OLED screen, another nRF radio module, and an Arduino Nano. You could put everything together on scraps of perfboard like ... oled, voltmeter, wireless.
