A couple of friends wanted to replicate the sprinkler system presented in this instructable but were scared by the complexity of it.
Well, it truly isn't complicated and it does not even require to solder anything if you pick the right parts... Since I long wanted to make the system more compact, I took the opportunity to make this solder-free arduino instructable. The system is very similar to (exactly the same as?) the previous instructable and just as open (supports scheduling, twitter etc...).
Connecting this arduino to your sprinkler system will allow you to remotely turn your garden watering on and off from any web-enabled device. From there you can make it as fancy or as simple as you wish.
Step 1: Collect parts
- 1 x arduino board
- 1 x ethernet shield (e.g. Ethernet Shield V1.0 for Arduino from http://www.nuelectronics.com )
- 1 x relay shield (http://seeedstudio.com/wiki/Relay_Shield)
- 1 x 10vDC adaptor (a recycled phone charger)
- 1 x momentary push button
You will not need:
- a soldering iron.
Step 2: Put it together
The push button is optionnal, it allows you to cycle manually through the sprinklers. Otherwise your only mean of control is the web interface... which is good too !
