Hand dryer

You definitely don't have something like this in your bathroom at home. You have a big towel hanging on a hook. But in public bathrooms, like the bathroom at your school or a restroom at a restaurant, you will often see electric blowers mounted on the wall that blow out hot air to dry your hands.

They are a great invention, especially ones that are so modern you don’t even have to push a button to turn them on. Simply hold your hands in front of them and they start up.

Now, you can use these building instructions to create a hand dryer with a touchless on and off switch, then wire it according to the wiring diagram.

Ask yourself the following questions before starting this task:

How is the hand dryer switched on? Does a control light switch on? When does the hand dryer switch back off? How long is the drying time?

Simply write the answers down on a sheet of paper, then use them later when you write your own programming commands.

We hope you enjoy working on this task.
