I'm new to Arduino and would like to try something out, the major part of which is counting the number of people entering/ leaving a room.
I thought of using IR sensors and even bought a 38KHZ IR detector, but I learnt that I've to know the analog pins part in the Arduino to make use of the detector.
So now I'm looking at using me-made pressure pads. When the pads are stepped on and released, the count should increase by one, but how do I know when the person is entering and when he's leaving? Also, a code or a video or a similar project link would greatly help me out! I use Arduino Uno.
