Regarding count value
Respected Sir/Madam When I try to upload the sketch given in the tutorial, when I press the pushbutton for the first time a count value of 0 is displayed. It should show as 1. Is (++count) or (count++) correct?

The ports in the program is different from the ports connected in the circuits diagram
Dear Sir/Madam ,In Display Counter Using Arduino partThe 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.

Outline:
Connect an LCD and a Push button to Arduino board. Use the same circuit created earlier using Arduino and LCD Add a pushbutton and make a simple counter Learn the connection circuit details See the live setup of the connection Write a program in the Arduino IDE write the code for void loop write a simple if statement to check whether the pushbutton is pressed or not Compile and upload the program See that pushbutton is working successfully Modify the program to set a counter Explain the error that occurs Write a while statement Again compile and upload the program Output: count is increased whenever the button is pressed
