lcd

A liquid crystal display or LCD display (English Liquid Crystal Display) is a display whose operation is based on electro-optical phenomena occurring in liquid crystals.

used: PC to display information

Used:

1. juhtmed
2. arduino uno
3. arendusplaat
4. lcd
5. potintsiomeeter

Code example

#include <LiquidCrystal.h>

// määrame, milliste digitaalpesadega ekraan ühendatud on

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

// loome erisümbolid
