Observe the program stack. The program is not working properly. What is the mistake here?
The FOREVER loop should be used instead of the REPEAT loop
The REPEAT loop did not indicate the number of repeats required
Pin 9, 10, 11 should be change to Pin 5, 6, 7
Observe the program stack for Running Light (turn LED on and off in sequence of 3 LEDs). Only one LED is working. What is the mistake here?
The FOREVER loop should be replaced with REPEAT loop
Missing <wait> block
Incorrect digital pin used
