The idea for this project was to count how many people are in a room at all times. Using a PIR motion sensor, movement would be picked up when someone entered the room by the door. The arduino IDE program keeps count each time the sensor is activated and increases the total variable. Finally the total number of people in the room is displayed on a mini LCD screen. I successfully got the sensor detecting motion and the total amount of activations displayed on the sensor, which can be (kind of) seen in the following (blurry) images.

Sadly, I didn't get finishing this project how I intended. I planned on getting another sensor to take off the total, accounting for when someone left a room. I had a good understanding and idea for this project, I just didn't have enough experience to complete it fully. However, I had a lot of fun messing around with this project. Figuring out how motion can be detected then using and displaying this data.

I came up with this idea originally in a Abertay Ethical Hacking Society meeting. In the code you may see reference to "Hacksoc" which is its abbreviation. The committee has to manually keep count of the total members that are attending each meeting, and report this to the Students Association. So then my idea, which was later found to be too ambitious for me at the time haha, was to count how many people were in a room at all times.

Maybe if I got it working as intended back then it would have sat at the door and counted the total members attending each week, and the committee would have just to look at the screen.
