Students have written code for controlling LEDs and other devices (the buzzer with the intrusion alarm, for example) and they have code for getting values from the analog temperature sensors. The soil moisture sensor code is actually easier because there’s no reason to convert the digitized voltage values into some “analog” equivalent. It should not be hard to write code that turns an LED on if the soil is really dry, for example. If students can do this, it is a good example of applying “computational thinking.”
