I started with a very basic version of a plantduino. In this version, plantduino reads the soil moisture and the temperature of the surroundings. Results displayed on a Nokia 5110 LCD screen and at different values of moisture it gives different messages like “what a lovely day!”, “keep calm and carry on!” and “hey dude! I’m thirsty!”

Next versions may include auto-pump system and tweeter integration.

For the nokia 5110 display you need the following libraries:

Adafruit_GFX.h

Adafruit_PCD8544.h

I have a problem on the code. At moisture values higher than 500 temperature adds 10 degrees and 20 degrees for values more than 600. I couldn’t find the problem, may be the connection of temperature and moisture sensor affects each other.
