Hand dryer with light barrier

Use the building instructions to build your second model.

Wire the model according to the wiring diagram.

For this model as well, I am going to give you a task and a secondary task. You then have to solve these by creating a control program.

Program the hand dryer so that when a user reaches through the light barrier, the motor with propeller starts up. When they take their hand back out of the light barrier, the motor must stop.

Of course, I will be helping you with this task too.

Just as with the previous task, start your Editor first.

Important: Once again, make sure you have activated the “Advanced” block with the appropriate button.

Before you begin programming, I need to introduce you to another sensor and actuator.
