To days Challenge !!
Design a model Electric Hand Dryer suitable for use in an
Engineering Room.
The dryer should activate automatically when a person
places their hand near the air flow and automatically switch off
after a set period of time.
Visual indicators are required to show that the unit is
operational or in standby mode.
The design should also include a means of visually
inspecting any electronics or mechanisms used.
The model must operate on a voltage supply of 9V or lower
and must not exceed 300 mm x 300 mm in size.

Control for Projects
How are PICs used?
• Purchased blank
• Inserted into a circuit board
• A control program is developed and tested on the computer and
downloaded to the PIC.
