Larry thought that he had the best way of getting around in the forest – he had read it an old book written by two brothers. Taking the remains of his breakfast sandwich, he left a trail of bread crumbs behind him to mark his trail. Naturally by mid-afternoon, he was hopelessly lost as the breadcrumbs he left behind mysteriously disappeared. While he had enjoyed the birdwatching that day (there seemed to be an unusually large number of birds gathering near him), there was no trail to be found! Those two “experts” were fakes. That’s the last time he’d trust anybody with the name like “grim”.
Right, he needed to get back to camp. He had a map … but which way to go?
- Using the in-built magnetometer to head towards any direction.
- Program to buzzer to beep repeatedly depending on how close the current direction is to the desired direction.
What Will Happen?
Press A to select the direction that you want to head and B to confirm. Following that, turn the compass to figure out where exactly you should go. As you turn towards the selected direction, the buzzer will beep repeatedly. The closer you are to the direction, the faster the speed of beeping. Once you have successfully figured out the direction, an arrow pointing towards the direction will appear.
- Add a servo motor that will mechanically point a physical arrow to the direction desired.
