Yup, its a drawing mistake. Actually the circuit works when the object moves very slow. But Its not working if object moves very fast. All I need is to improve fraction time.
Hi, Sorry for the inconvenience. Let me explain my project briefly.
Photo-diode and LED will be placed in approx 5cm distance. When the light falls on photo diode it has to give a logical high/Low output. If no light it has to give opposite output. But the problem is. Object is crossing the...
My project is to detect the object passing through the photodiode and count it. But the problem is, the object passing the photodiode in fraction of seconds(in milliseconds) it makes very small amount of voltage difference in the output pin of the comparator. Google says we have to use...
