Initial Design Build Draft

My solution is a door alarm that not only alarms you of somebody coming in it stops them from coming in. so my alarm will sense when somebody comes near the door and that will tell the motor to lock the door. Next an alarm will tell you that somebody is coming in. By using the NXT program I was able to program it so that the ultrasonic sensor will sense when somebody comes near the door. This will tell the motor to lock the door. Next the NXT will make a noise.
I think my solution is the best because lets say you are wrapping a present for your brother/sister’s birthday. My door alarm solution will stop intruders from entering as well as alarming you.

I have just found a problem that my motor is not able to hold on to the door with tape.
