Solar mini assignment (new): Measure the power required to run a microcontroller. Take any project you already have, and using your multimeter, measure the current needed to power the project. As you already know the voltage, you can determine the power (V*I). If your microcontroller does different things, like turn on and off an LED, or connect to a wifi network and send a message, make sure to measure the curent required for each stage. Record your results on your blog.
