Hello!!
I am having some problems with programming LCD screen and if statements, everything should work a part of anything related with LCD. Can i ask you an advice on this?
- after touching the touch sensor: lcd.write(pause)
- after touching the touch sensor when led is up: lcd.write(snooze)
- if(cronometro== 5 : lcd(move)
- if(cronometro== 20) : lcd.write(get up!)
- if((cel>30) && (cel<33)){digitalWrite(bluePin,HIGH): lcd.write(relax)
-if((cel>=33) && (cel<37)) : lcd(anxious)
How can i write those? and how can i make the disappear?
Thank you very much
thank you:
