The important aspects of the intended design are as follows:
- Rather than using a simple timer system, this plant watering system will utilize an Arduino board (a programmable microcontroller) as its control.
- The product will be aesthetically pleasing, since it is for consumer use. No circuit boards or motors should be visible in the final product.
- The system will be able to support up to 3 plants.
The basic intended structure of the system is laid out in Figure 1. The Arduino control system communicates with the pump, which responds to the Arduino commands and pumps water from the reservoir through plastic tubing into the plant's soil.
