Plant Watering System – Overview

Hello Embedded Systems Fans!

It’s that time of the year – finals! Which means it’s time for our final project. The Unknowns were working night and day trying to decide what project we wanted to do, when it dawned on us…. we’d forgotten to water out plants!

Luckily, they were able to be saved, but it sparked the idea; “what if there were a system which would figure out when our plants needed watering, and would do it for us?” And so came about the big idea for our final project – an automatic plant waterer! All we would need is our handy-dandy Atmega328P Xplained Mini, a motor driver, a water pump, and a soil moisture sensor (shown below).

Plant Watering System: Code

Hey there Embedded Fans!

Progress is being made on our plant watering apparatus! As of late, the Unknowns have their code in progress, and we’ve gotten our motor driver to work! In order to do this, we’ve sent a high and low signal to two of the input pins on the driver (from pins D6 and D7), and sent a high signal to the enable pin (from pin D5) ! See our code snippet for super cool and exciting bit shifting operations!

But… don’t listen to me – see for yourself!

Soon our plants will never go thirsty again! :,)
