I have a project which requires me to turn on the light in a room when there are people present in it. I am using an Infra red emitter and a photodiode as the sensor. I intend to put 2 sensors with a difference in distance inorder to be able to differentiate between people entering and exiting.
I have not worked with counters before and I have no Idea on how I can connect it to the 877 PIC. I need some help in that, please!
I also have a problem on how to use the up mode and the down mode of the counter.
Thank you!
