Arduino.ru

вы этот код явно откуда-то списали, в нем в строчке 24 упоминается какой-то "мануал" - может стоит его найти и почитать?

Мануала я не нашел.

Вот откуда я взял этот код.

Все ссылки ведут либо на несуществующие страницы, либо на скетч, либо на википедию

http://lcdsmartie.sourceforge.net/ - все там ок. Даже форум имеется.

Я нашел чуть другой скетч для ардуины, только он без I2C

Как можно переделать его на I2C?

в качестве идеи - заменить библиотеку LiquidCrystal.h на LiquidCrystal_I2C.h ?

А как можно почту добавить?

Что нужно вводить?

SAn4Es_TV , форум не чат, не надо тут все подряд спрашивать

Как можно подключить кнопки что бы они работали с программой?

3-тий день пытаюсь найти решение

707й, тебя игнорят...

Тема была создана для ОБЩЕГО подключения к ардуине всей нужной электроники(Дисплей, кнопки) так, чтобы она работала с LCDsmartie
