inputs and outputs

For my homework I have to write on my blog the different inputs and outputs needed in sliding door.

The input needed for the sliding door I chose (my design) is:

• A laser sensor

The outputs needed for my sliding door design is:

• motor:door opening
• motor:door closing

Decision:

• Is there someone going through
• Is there motion
• Is there anyone else going through

Because I have a laser sensor when people go through the door opens quickly with a delay of six seconds and the door can also sense if there is anyone else waiting. For handicapped people the door can sense them and give thema delay on ten seconds.
