DIY Voltmeter and Ammeter using a Microcontroller || AREF || Voltage Divider || ACS712 || INA219

Edit: 1:50 R1 is 33k and R2 is 6.8k.
If you ever felt the need of continuously monitoring the voltage or current or both in a project, of any device or the project itself, you have come to the right place. In this video, I'll show you how you can measure current and voltage with your microcontroller and hence you can perform your said operation according to it. You'll learn what can we do with the mostly unused AREF pin of Arduino, Voltage Divider and how to use ACS712 and INA219.
