Acs712 Ac Current Measurement Arduino Code

Acs712 current sensor can measure both direct and alternating current. Hello and welcome to another tutorial this one is about measuring alternating current ac using acs712 i m using the 30amps version which is acs712 30a and our lovely arduino uno board i tried to add an oled screen but unfortunately ended up breaking it while shooting the tutorial so i switched to the lcd but below you ll find the. What is very important is also have internal low drift volt.
