Hello, This time I will show an application of the infrared sensor module with Arduino.
This module (composed of a pair of LEDs, a infrared transmitter and a receiver and an IC that generates a frequency modulated) is generally used to detect obstacles in robots.
This module has some advantages over a simple LED emitting LEDs with a photodetector. The principal, in this case is that the emission frequency is modulated, preventing ambient light makes the receiver detect the wrong signal. Also, the construction module that facilitates interconnection and didactic use with the Arduino.
Step 1: Materials
- An Arduino board
- A sensor shield board
- 3 infrared sensor modules
- A standard servomotor
- A Styrofoam ball
