DataCollection
1. Check the MudWatt™ each day to see if the LED light is blinking.
2. Use the MudWatt Explorer app to measure and record the amount of current
being produced (the app converts the number of blinks per minute the LED
light produces into power in microWatts (μW)).
3. Record the power output each day for 20 days in the data table. If the light is
not blinking, record the value as 0.

Graphing
Once all the data have been collected make a graph of the voltage (y axis)
versus time (x axis). Be sure to include a title, axes labels, and units.
