Channel "Electronics in the lens" - / @rnadyrshin
In this video I will show you how to assemble THREE variants of simple voltmeters based on Arduino. The first option is the simplest - a voltmeter on the Arduino, the readings from which will be output via a serial connection to the "Serial Monitor". Next, we will finalize this sketch and connect the LCD screen, as a result we will get an Arduino voltmeter with an LCD screen. And the third option is to build not just a voltmeter, but a volt-ammeter on Arduino by adding a few lines of code. I will also show how to find out the address of the I2C module, how to use it and how to connect the LCD screen with the I2C module to the Arduino Uno board.
