Arduino Workshop - Project 4 Errata

0 comments
This is an errata for Arduino Workshop, Project 4, Page 67 (PDF version).

The instructions for the push button do not include running a cable from Arduino 5V pin to the pushbutton. Without it, no voltage runs to pin 7 and the example does not work.

Below you can see the photo of a working circuit:

Replace this code:

for ( int a = 5 ; a > 1 ; a-- )
 {
 digitalWrite(a, HIGH);
 delay(d);
 digitalWrite(a, LOW);
 delay(d);
}

with

for ( int a = 6 ; a > 1 ; a-- )
 {
 digitalWrite(a, HIGH);
 delay(d);
 digitalWrite(a, LOW);
 delay(d);
}

Note "int a = 6". Without this update, one of the LEDs will not blink.
