== Home automation - Automatic watering of Plants (IoT) ==<br />
<br />
<br />
=== Hackathon scope ===<br />
<br />
'''Challenge:''' Create and demonstrate a simple watering strategy for plants with Arduino<br />
<br />
'''Time''' 3 hours<br />
<br />
'''Limits''' The scope of this challenge is focused on the accomplishment of the watering. Connecting it to the cloud for logging and remote control is outside the scope this time.<br />
<br />
=== Awards ===<br />
* Most creative overall solution given the starting components<br />
* Best watering solution<br />
* Best sensor solution<br />
* Best control loop strategy<br />
* Most robust solution<br />
* Most pimped solution<br />
<br />
<br />
=== Presentation ===<br />
Show and tell with mingle and demonstration together afterwards.<br />
<br />
It's a hackathon! Focus on demonstration and proof of concept. Fake it and explain how you are thinking!<br />
<br />

<br />
With an Arduino Microprocessor and a servo, a relay and some analog inputs/outputs you have the foundation of a simple home automation system. A push of the button should get things moving right away!<br />
<br />
'''Start kit'''<br />
<br />
Every kit has a basic setup for movement and an additional component that might vary between teams (valve, pump, motor, extra servos)<br />
<br />
[https://github.com/kriffe/Arduino-Start-Template Starting code skeleton] to get you on the way can be found on [https://github.com/kriffe/Arduino-Start-Template GitHub]<br />
<br />
Should be working with servo movement and relay activation on button press.<br />
