I needed a device to time my sprinklers, because I had been forgetting to turn them off. So I made a very simple program to turn them off after 45 minutes. Future versions will have an array of outputs, so you can run sections with one button push. Hardware: Either board should work, I used the LPC1768. You will also need a solenoid to control the water, I am testing a 12V rainbird valve with a relay and 12V power supply.

Sprinkler Timer¶
I needed a device to time my sprinklers, because I had been forgetting to turn them off. So I made a very simple program to turn them off after 45 minutes.
Hardware¶
- Tested on the LPC1768
- Either board should work
- You will also need some way of controlling the flow of water (like a solenoid valve and a relay). My test equipment:
- 12V Rainbird valve
- relay (SainSmart 2 channel relay)
- 12V power supply (must be able to run the solenoid)
Future¶
Future versions will have an array of outputs, so you can run sections with one button push.
