The ports in the program is different from the ports connected in the circuits diagram
Dear Sir/Madam ,
In Display Counter Using Arduino part
The circuit diagram shows (in 0.50 sec) the ports 11,10,9,8 in the Arduino are connected to pin number 11,12,13,14.
But in the program (in the line no.2) you have mentioned port numbers as 5,4,3,2. where in the these pins are unconnected.
Kindly change the program or the code respectively.

We have explained the connection details and pins of LCD in the previous tutorial "Arduino with LCD". Please go through the tutorial and understand the connections. The same circuit connection is used in the next tutorial "Display Counter using Arduino".
In Arduino with LCD tutorial,
1:31 - We have explained the data pins of LCD as D0 to D7
7:43 - We are saying "d4, d5, d6 and d7 of LCD are connected to pins 5, 4, 3 and 2 of the Arduino board".
The same connection is shown in "Display Counter Using Arduino at (0.50).
5,4,3,2 of Arduino (yellow wire) is connected to data pins of LCD.
Please see the circuit connections in full screen. There is no error in the code or in the circuit diagram.
