Description

The TCRT5000 is a commonly used infrared sensor module that is used in a variety of robotics and electronics applications. It consists of an infrared LED emitter and a phototransistor that are mounted side-by-side. The LED emits infrared light, which is reflected off of any object that it comes into contact with. The phototransistor detects the reflected light and outputs a voltage that is proportional to the intensity of the light.

The TCRT5000 can be used to detect objects, track lines, and measure distances. It is a relatively inexpensive and easy-to-use sensor, which makes it a popular choice for hobbyists and makers.

Here are some of the specifications of the TCRT5000:

• Operating voltage: 3.3V to 5V
• Output: digital (high or low)
• Sensing distance: 1mm to 25mm
• Adjustable sensitivity

3. Wire male to female.

Step 3: Pin Connection

           

Step 4: Sample Source Code

const int pinIRd = 8;
const int pinIRa = A0;
const int pinLED = 9;
int IRvalueA = 0;
int IRvalueD = 0;
void setup()
{
  Serial.begin(9600);
  pinMode(pinIRd,INPUT);
  pinMode(pinIRa,INPUT);
  pinMode(pinLED,OUTPUT);
}
void loop()
{
  Serial.print("Analog Reading=");
  Serial.print(IRvalueA);
  Serial.print("\t Digital Reading=");
  Serial.println(IRvalueD);
  delay(1000);
  IRvalueA = analogRead(pinIRa);
  IRvalueD = digitalRead(pinIRd);
}Copy
