The field where the frog will jump needs only some tape to mark the location of the eggs.
The program starts with a 3-second wait and a sound signal. Students should wind the legs of the frog backwards during these 3 second and leave the frog by the eggs when the signal is given.
The following two tasks aim at helping students find out the sign of the wait block.
Finally, the program ends by rotating motor D forward until it reaches more than 0 degrees after which it should stop. And again, be careful with the ports :).
