Battery Operated Drip System
My aim was to create a battery operated drip system, that could easily be installed anywhere in the garden.Once a day, for a preset number of minutes, the unit waters the plants via a little 9V operated pump that is submersed in a 20 Liter bucket.See the picture of the end result above: the unit is screwed onto a little wooden plate , and connected to the garden fence. The bucket is situated next to it, and two little wires lead towards the submersed pump. The pump will then supply the water to a tiny hose with some dripper heads.Extremely low power consumptionI found a link to a site that describes how to use the Atmel chip that is present in an Arduino Uno in a standalone fashion, with a library that allows for extremely low power consumption. This helped realise a design that is extremely low in power consumption. The batteries will last for a few years.RequirementsSetting the number of minutesThe yellow led on the left flashes will flash after every 15 seconds. Then it will flash
