What does this Arduino code do? This code will make a servo motor rotate from 0 to 90 degrees in increments of 1 degree with a 15ms delay between each increment, then rotate back from 90 to 0 degrees in the same way. This code will make a servo motor rotate from 0 to 90 degrees in increments of 2 degrees with a 15 ms delay between each increment, then rotate back from 90 to 0 degrees in the same way. This code won't work well because it will command the servo to instantly try to jump between 0 and 90 degrees, and the servo won't be able to keep up. This code will make a servo motor rotate from 0 to 180 degrees in increments of 2 degrees with a 15 ms delay between each increment, then rotate back from 180 to 0 degrees in the same way
