The answer was too long for the comments section so i ve extended into a blog post.
Ir break beam sensor arduino code.
Ir break beam sensor 3mm leds.
The source code is the same as for the hall effect.
Here s an example of wiring to a feather m0.
The output from the receiver connected to pin 8 goes low when it detects 38khz modulated ir light and high when the beam is broken.
14 wires only 10 are pictured but 14 will be used an arduino uno.
Ir breakbeam sensor demo.

Teensy 2 0 has the led on pin 11 pin 6.
Infrared ir break beam sensors are a simple way to detect motion.
Define ledpin 13 pin 13.
They work by having an emitter side that sends out a beam of human invisible ir light then a receiver across the way which is sensitive to that same light.
We explain how to wire up a beam break sensor to use on your robot.
Infrared ir break beam sensors are a simple way to detect motion.
One straightforward way is to use the library to modulate an ir led at 38khz and use a standard ir detector module to detect the signal.
Teensy 2 0 has the led on pin 11 pin 6.
Int sensorstate 0 laststate 0.
Ir break beam sensor 5mm leds.
Arduino has an led connected on pin 13 pin 11.
This guide was first published on dec 10 2014.
This page overview.
Arduino has an led connected on pin 13 pin 11.
Very easy to program the arduino around.
First wire up a break beam transmitter and receiver just like you would for an arduino.
It s easy to read a break beam sensor from circuitpython code using built in digital input output capabilities.
Teensy 2 0 has the led on pin 6 pin 13.
Upload this code to arduino.
Teensy 3 0 has the led on pin 13 define sensorpin 4 variables will change.
And the photodiode is connected to 5k ohm of the resistor in series to 5v of supply and signal is taken out from it which goes to the analog input pin of arduino.
Pin 12 is connected to a relay module also powered from the external voltage regulator by 4 5v.
Variable for reading the pushbutton status void setup initialize the led.
Teensy 2 0 has the led.
