Hello,
I follow this course : https://www.youtube.com/playlist?list=PLGs0VKk2DiYw-L-RibttcvK-WBZm8WLEP
on lesson 5 I had to make a digital counter with led's.
So I did it this way
loop() {
// 1 = 1
digitalWrite(greenPin1, low);
digitalWrite(greenPin2, low);
digitalWrite(greenPin3, low);
digitalWrite(greenPin4, High);
// 2 = 2
digitalWrite(greenPin1, low);
digitalWrite(greenPin2, low);
digitalWrite(greenPin3, High);
digitalWrite(greenPin4, low);
....
is there a better way to make this work so it counts to 15 without a lot of the same code.
and if so , can someone explain to me how that code works ?
