To create some tests with the project, you will also need a device to test. I made the test
with a typical 30W desk lamp, but you can choose the AC device of your choice.
Note
The current sensor is made to measure high currents, so don't take a small AC device or
the current readings might be incorrect.
However, on some boards that host the ACS712 current sensor, you have the possibility to
change the sensitivity of the current's measurement. So, you might be able to measure
lower currents and powers depending on the board you are using.
The following are the hardware requirements:
• Arduino Uno (

)
• Adafruit CC3000 breakout board (

)
• ACS712 module (

)
• Breadboard (

)
• Jumper wires (

On the software side, you need to have the latest version of the Arduino IDE installed on
your computer as well as the CC3000 chip library:
