(DC MOTOR) 555 TIMER VIA IR LED & RECEIVER

Hello Guys, about our project the main objective is that when something blocks the ir receiver to the ir led the dc motor will turn on. The question is that how can you tell a quick detection and a long detection using IR sensors (IR LED & IR Receiver) ?

The circuit is attached below…

This sounds like a project for a class.

Most people would use a uP (8 pin will do), a simple program and eliminate most of the components shown.
