Watering your plants

We are now going to utilize every component we created in the past sections. Putting everything together, we will be building a completely automated plant watering system.

To start off, we need to create a new folder named plant-watering-system inside the Chapter04 folder. Inside the new folder, create a new main.go file with an empty main() function inside. The final project structure should now look like the following:

Figure 4.17 – Project structure for plant watering system

Now, inside the main function, follow these steps:

1. Initialize the ADC interface:

   machine.InitADC()

2. Initialize a new soilSensor:

   soilSensor := soil.NewSoilSensor(18000, 34800, machine.
                 ADC5, machine.D2)
   soilSensor.Configure()

3. Initialize a new waterLevelSensor:

   waterLevelSensor := waterlevel.NewWaterLevel(7000,
