Count people through a door, animals through a space, products on an assembly line... This experiment uses the same Infrared LED and Sensor setup as before to detect inputs on a Raspberry Pi using interrupts in Python 3.
A relatively simple python program allows you to power the LED and use the photodiode to detect any interruption of the IR beam. Can be used for counting, detection of objects, location of moving parts, etc.
MATERIALS
IR photodiode
IR LED
330 ohm resistor x2
1M ohm resistor
Jumpers
Breadboard
Pi
WARNING: Warning: mis-wiring or mis-programming your Pi or miswiring of accessories can ruin the Pi and accessories.
