its a code that identifies which pin of the LCD that is used: 12 and 11 stands for the RS(Register selection) and R/W(Read/write) pins of the lcd while 5,4,3,2 represents the D4 – D7 pins of the lcd as we are using 4bits instead of the usual 8bits which consist of the D0-D7

Hopefully you can help. Thank you.

Class / object / function / module…. ………. ?

Como se modificaría el sketch de modo que la visualiza la barra de progreso y su respectivo porcentaje de avanze ( 0 % ………100%).
Saludos…

En mi caso el código no corre, hay comandos en español, se debe cambiar al ingles.
Por ejemplo … lcd . comenzará (16 , 2 )… ; debe decir LCD.begin(16,2) .
He visto que muchos escriben en español y les funciona, porque? en el programa Arduino 1.0.5-r2, que utilizo, los sketch me acepta codificación de comandos en ingles.
