egg_incubator:258: error: request for member 'year' in 'now', which is of non-class type 'int'
jag misstänker är man kanske behöver nått till lägg för det verkar som att den inte förstår datum och tid
den hårdvara jag har nu är
DTH22 fukt/temp sensor
Arduono uno rv3 "starter kit" så lite motstånd dioder mm
men ingen minneskort display mm som han haft som jag hitta koden hos
men det borde väl gå bra att låta det vara kvar utan att jag har den hårdvaran kanske ska skaffa det sen men börja med att köra med datorn inkopplad.
vore tacksam om jag kunde få lite hjälp jag håller på att försöka lära mig grunderna än.
är kommer koden

får inte till en sån där scroll lista någon som vet hur man gör så det blir lättare att läsa så ändrar jag koden
