It s easy to read a break beam sensor from circuitpython code using built in digital input output capabilities.
Ir break beam sensor arduino code.
Here s an example of wiring to a feather m0.
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.
14 wires only 10 are pictured but 14 will be used an arduino uno.
The source code is the same as for the hall effect.
Arduino has an led connected on pin 13 pin 11.
Infrared ir break beam sensors are a simple way to detect motion.
We explain how to wire up a beam break sensor to use on your robot.

Ir breakbeam sensor demo.
Arduino has an led connected on pin 13 pin 11.
Teensy 2 0 has the led on pin 11 pin 6.
This guide was first published on dec 10 2014.
Pin 12 is connected to a relay module also powered from the external voltage regulator by 4 5v.
First wire up a break beam transmitter and receiver just like you would for an arduino.
This page overview.
Infrared ir break beam sensors are a simple way to detect motion.

Define ledpin 13 pin 13.
Very easy to program the arduino around.
Teensy 2 0 has the led on pin 6 pin 13.
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.
Teensy 3 0 has the led on pin 13 define sensorpin 4 variables will change.
Ir led is connected with 100 ohm of the resistor in series to the digital pin of arduino.
Teensy 2 0 has the led.
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.
One reader asked how to use my arduino infrared library to detect breakage of an ir beam.
We explain how to wire up a beam break sensor to use on your robot.
Variable for reading the pushbutton status void setup initialize the led.
Ir break beam sensor 3mm leds.
Ir break beam sensor 5mm leds.
Int sensorstate 0 laststate 0.
Teensy 2 0 has the led on pin 11 pin 6.
The answer was too long for the comments section so i ve extended into a blog post.
