In this article you will find out what an IR sensor A is and how to use it
DESCRIPTION
The sensor contains 2 elements: an infrared LED that emits light in the infrared range, and a sensitive photocell. If there is a reflective surface near the sensor, part of the light returns to the photocell. The closer the surface and the “whiter” it is, the more light returns to the receiver, the higher the sensor readings. The sensor transmits a value between 0 and 1023.
The IR sensor A is Lego- and Arduino-compatible.

Technical description:
– Size (L*W*H): 40x24x24
– Lego compatible body
– (PIN A) The sensor detects the reflection of the light signal and sets the analog value on PIN A corresponding to the intensity of the reflected light
– Working voltage: 5V
– Connector for connecting to another device: F-dupont 3pin

Functionality when connected to the RED X controller:
The infrared sensor registers the amount of reflected infrared light.

RED Code Example
*Physically, if the IR sensor D sensor connected to port D2 reads white colour, then the servomotor connected to port D1 rotates by zero degree, otherwise the servomotor rotates by 180 degrees
