So I'm learning Arduino via Youtube and was trying to modify this code a little and experiment.
The program worked fine up until I added the variable user inputs. It will sit there displaying the first two lines of text as expected and I enter an number, then somehow a 0 get put in for the input for the second variable, and then it sits and waits for the third input, skips the fourth just like the second and waits for the fifth input.
Anyone know how to correct this so it doesn't put a 0 in for input 2 and 4?
Oh btw the program is to ask a user how many times a set of 5 LEDs should blink
Thanks in advance for anyone who responds
This is what is displayed
"Welcome to my Program
How many times do you want the Red LED to blink?
2
How many times do you want the Green LED to blink?
0
How many times do you want the Blue LED to blink?
3
How many times do you want the Yellow LED to blink?
0
How many times do you want the White LED to blink?"
