Arduino power logger - DIY

Welcome back. Today we will build a power meter using Arduino. We already build the current meter in a past tutorial and also a capacitance and resistance meter and the inductance meter. Check all those tutorials here and learn more.
Now, power is voltage times current, so using the same model as in the current meter, we will build today a power meter. I want it to display the voltage, current and power. This would be a very useful tool while working on my projects, since I could measure the power that one component will draw. So, let’s gather all the components and start this project.”
