    Keep in mind the schematic

    Following this diagram can seem very complex for a beginner, but you need only to pay attention to the pins and their position (if you prefer you can also download the file with the diagram).

    Build up the tin maze!

    Following the path described in the diagram connect the jumpers to pins using the soldering iron, if you are a beginner you can use also the breadboard.

    At the end of this instruction you should have a structure very similar to a maze.

    Like this...

    Remember if want to manage the output cables in a more ordinated way you can use also JTS connectors like these

    connecting the jumpers to their pins.

    Test your prototype!

    Now your prototype is ready to be tested, so connect it to your microcontroller and run this script always paying attention to the connections 

    #include <LiquidCrystal_74HC595.h>

#define DS 8
#define SHCP 6
#define STCP 7
#define RS 7
#define E 5
#define D4 4
#define D5 3
#define D6 2
#define D7 1

LiquidCrystal_74HC595 lcd(DS, SHCP, STCP, RS, E, D4, D5, D6, D7); //Pins association

void setup() {
  lcd.begin(8,2);//Defining columns and rows
 
}

void loop(){
  lcd.print("Hello World!");//Printing the message
}

     If the code is not very clear here I'll include the file in   the files section.

    The current code is written in C++.
