As a newbee I have trying to writing a program button push counters with 4 switches.
but I do not manage to make a 4 switch counter which creates a column with the values of the switches each time when switch 1, 2, 3 or 4 is pressed. I have attached the program. My program will not stop after I press a button and it generates random values. What do I wrong. Can somebody gif me a hint.
The column to be created should look like this, every time when a switch is pressed
switch1 switch2 switch3 switch4
1 0 0 0
0 1 0 0
0 0 0 1
My program
