Assignment

• Smil Chapter 4
• Review the work of Trash Club, in particular the projects, readings, resources.
• 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.

Response

I measured the power required to run the Arduino Nano 33 IoT that was powered by a geared DC motor from the kinetic project.

The current needed to power the project is between 20-40 milliamps and the voltage is around 5 volts. The power is between 1 and 2 watts.
