Arduino - EM18 RFID Reader

In this Project, we will see about how to interface EM-18 RFID with Arduino.

Circuit Diagram:

Arduino Code:

rfid_receive_char_code.ino

void setup() {
  Serial.begin(9600);
}

void loop() {
  if (Serial.available() > 0) {
    char inChar = (char) Serial.read();
    Serial.println(inChar);
  }
}

rfid_receive_string_code.ino

boolean stringComplete = false;
String inputString = "";
int n = 0;
#define BUZZ 8

void setup() {
  Serial.begin(9600);
  pinMode(BUZZ, OUTPUT);
  inputString.reserve(200);
}

void loop() {
  if (stringComplete) {
    Serial.println(inputString);
    if (inputString.equals("180001493565")) { //A
      digitalWrite(BUZZ, HIGH);
    }
    if (inputString.equals("1300711F7508")) { //B
      digitalWrite(BUZZ, LOW);
    }

    stringComplete = false;
    inputString = "";
  }
}

void serialEvent() {
  while (Serial.available()) {
    n++;
    char inChar = (char) Serial.read();
    inputString += inChar;
    if (n >= 12) {
      n = 0;
      stringComplete = true;
    }
  }
}

Arduino - LED Blinking

In this Project, we will see about how to control LED with Arduino by Simple Code.

Circuit Diagram:

Arduino Code:

led_blinking.ino

void setup() {
  pinMode(LED_BUILTIN, OUTPUT);
}

void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (+5V level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off (0V level)
  delay(1000);                       // wait for a second
}
