YouTube Project Series Video 03 - Plant Water Reminder Device

My third YouTube video! This video is about my plant water reminder device. It is a box that has a moisture sensor attached that reads the moisture value of a plants soil. It then sends notifications to a phone if the moisture level is too low. Good for lazy people like me!
In the video it shows the build and coding process, plus challenges and future improvements.
