Cheap tank fill and gardening automation

delay(3 hrs or 3*3600*1000 milli seconds)

delay(random(0,20)*60*1000 milli seconds) # a small naturalisation randomisation time

pin2= 1 ( switch on relay to solenoid valve for 200 re with 20 re relay and 2 re transistor with )

delay(29 mins or 20*60*1000 ms)

pin2=0 ( switch off sprinkler)

}

keep looping in attiny or AVR or arduino prototype

With direct transistor and solenoid it will be residential code but with a relay its 220 V motro for 1 km squared farm
