82 Five road tracing module tracing sensor 5 functions to send routines TCRT5000 Five Channel tracking module

Description:

The BFD-1000 sensor module is a multi-sensor module that can be used to create a line follower robot that can accurately track a black or white line. The module is designed with 5 TCRT5000 sensors for line tracking and black road detection and an IR proximity sensor in the front. This combination of sensors makes it easy to create a robot that can accurately follow a line, even on complex tracks, The TCRT5000 sensors are designed to detect the contrast between a black line and a white background, which makes them ideal for line following. They have a detection range of 0-4cm, which means that they can detect the line even when it is very close to the ground. The sensors are also highly sensitive and can detect lines with a sensitivity range of 0.5mm-40mm without any adjustment. The front IR proximity sensor is designed to detect obstacles in front of the robot. It has an adjustable detection range of 0-5cm, which means that it can detect obstacles at varying distances. The sensor operates on an input voltage of 3.0V-5.5V and outputs digital signals (high and low level) that can be easily connected to a microcontroller. The module also has LED lights as indicators for easy debugging. The BFD-1000 sensor module is designed with a special touch sensor design, which simplifies the robot's design. The sensor outputs all digital signals, which makes it easy to connect to a microcontroller. The module also supports a voltage of 3.0-5.5V, which means that it can meet any system requirements.

Circuit:

• VCC pin of the module to 5V pin of Arduino
• GND pin of the module to the GND pin of the Arduino
• S1 to digital pin 8 of Arduino
• S2 to digital pin 9 of Arduino
• S3 to digital pin 10 of Arduino
• S4 to digital pin 11 of Arduino
• S5 to digital pin 12 of Arduino
• CLP to digital pin 6 of Arduino
• Range finder sensor to digital pin 7

Code:

A basic code  forreading the sensor values from the BFD-1000 module and displaying them over serial: 

const int line_pin[5] = {8, 9, 10, 11, 12};
const int near_pin = 7;
const int clp_pin = 6;
int line_val[5] = {0};
int near_val = 0;
int clp_val = 0;

void setup() {
  Serial.begin(9600);
  for (int i = 0; i < 5; i++) {
    pinMode(line_pin[i], INPUT);
  }
  pinMode(near_pin, INPUT);
  pinMode(clp_pin, INPUT);
}

void loop() {
  read_sensor();
  display_serial();
}

void display_serial() {
  for (int i = 0; i < 5; i++) {
    Serial.print(line_val[i]);
    Serial.print(" ");
  }
  Serial.print(near_val);
  Serial.print(" ");
  Serial.println(clp_val);
  delay(1000);
}

void read_sensor() {
  for (int i = 0; i < 5; i++) {
    line_val[i] = digitalRead(line_pin[i]);
  }
  near_val = digitalRead(near_pin);
  clp_val = digitalRead(clp_pin);
}

• The first 6 lines of the code define the pins that the sensors are connected to. The 5-line sensors are connected to pins 8-12, the proximity sensor is connected to pin 7, and the touch sensor is connected to pin 6.
• In the setup function, the code initializes the serial communication with a baud rate of 9600 and sets the pin modes for the sensors as input.
• In the loop function, the code calls the read_sensor function and then the display_serial function.
• The read_sensor function uses a for loop to read the values of each of the 5 line sensors, the proximity sensor, and the touch sensor and stores these values in corresponding variables.
• The display_serial function then prints out the values of the sensors to the serial monitor. It does this by using another for loop to iterate through the line_val array and printing out each value, followed by printing the values of the proximity sensor and the touch sensor.
• The code then adds a delay of 1000ms (1 second) before starting over again.
