I have used 12V lamp as a load and have measured its current using this ACS712 current sensor and Arduino. I have displayed the values over to LCD 20 x 4. Here's the code which I have used for this ...

The circuit is built around Arduino Uno board (Board1), current sensor IC ACS712 (IC1), 16×2 LCD (LCD1), npn transistor BC547 (T1), piezo buzzer (PZ1) and a few other components. Fig. 1: Circuit ...

The main component used is the ACS712 sensor from Allegro MicroSystems to measure the current. It provides economical and precise solutions for AC or DC current sensing in industrial, commercial and ...

It's a simple one but used in a lot of engineering projects. IT comes in handy if you want to increase your battery life as using this sensor you can be aware of your major power consumers and thus ...
