Have a question but, here is the idea of the project first.
Using a ping sensor to find the distance of an object.
the ping sensor would be mount at the edge of the door looking for objects.
when and object is detected at a set range the door will be stopped and not allow to open more.
note: that the ping sensor will be moving and a range of how close the door can get will be set.
can a arduino be fast enough to do this calculation?
calculation being crunch the numbers coming from the ping sensor and stopping the door, via output a signal to the stop device, at a set distance.
New to the arduino but not to the avr/atmel world
Thank in advance for the help.
