Data not displaying on crystal screen
hello guys, im trying implement ethernet code code able transmit data (humidity, temp , distance) carriots. on havent figured out how yet first things first , getting arduino connected internet.
the system thesis project , opens valve x seconds every y minutes , transmits data dht22 on crystal screen. have implemented distance sensor should measure amount of water left in reservoir, although im still working on that.
purpose broadcasting data internet(carriots) can follow system home.
whenever add ethernet.begin(mac,ip); in void setup() data dht22 doesn't displayed on creen. when delete line works again.
how can solve this? im not computer scientist

code: [select]
liquidcrystal lcd(12, 11, 5, 4, 3, 2);
the communication between arduino , ethernet shield happens via spi, uses pins 10, 11, 12, , 13. can't connect lcd of pins.
