Pin Configuration

  • Mini Electric Drill Set Component Documentation
  • Pinout Description:
  • The Mini Electric Drill Set component has a total of 6 pins, which are used to control and power the device. Below is a detailed description of each pin, including its function and connection guidelines.
  • Pin 1: VCC (Positive Power Supply)
  • Function: Supplies positive voltage to the drill set's motor and internal circuitry.
  • Connection: Connect to a suitable power source (e.g., battery or voltage regulator) with a voltage range of 3.7V to 12V.
  • Note: Ensure the power source can provide sufficient current to drive the motor.
  • Pin 2: GND (Ground)
  • Function: Provides a common ground connection for the drill set's internal circuitry.
  • Connection: Connect to the negative terminal of the power source or a common ground point in the system.
  • Pin 3: EN (Enable)
  • Function: Enables or disables the drill set's motor. A logic high (VCC) on this pin enables the motor, while a logic low (GND) disables it.
  • Connection: Connect to a digital output of a microcontroller or a logic-level signal source.
  • Pin 4: DIR (Direction Control)
  • Function: Controls the direction of the drill set's motor. A logic high (VCC) on this pin sets the motor direction to clockwise, while a logic low (GND) sets it to counterclockwise.
  • Connection: Connect to a digital output of a microcontroller or a logic-level signal source.
  • Pin 5: PWM (Pulse-Width Modulation)
  • Function: Controls the speed of the drill set's motor using pulse-width modulation. A PWM signal on this pin adjusts the motor speed.
  • Connection: Connect to a PWM output of a microcontroller or a dedicated PWM signal source.
  • Pin 6: SENS (Sensor Output)
  • Function: Provides a digital output indicating the drill set's motor status (e.g., rotation detection, overcurrent detection).
  • Connection: Connect to a digital input of a microcontroller or a monitoring circuit.
  • Connection Structure:
  • To connect the Mini Electric Drill Set component, follow this structure:
  • Power supply:
  • + VCC (Pin 1) -> Positive terminal of the power source
  • + GND (Pin 2) -> Negative terminal of the power source or common ground
  • Control signals:
  • + EN (Pin 3) -> Digital output of a microcontroller or logic-level signal source
  • + DIR (Pin 4) -> Digital output of a microcontroller or logic-level signal source
  • + PWM (Pin 5) -> PWM output of a microcontroller or dedicated PWM signal source
  • Feedback signal:
  • + SENS (Pin 6) -> Digital input of a microcontroller or monitoring circuit
  • Important Notes:
  • Ensure the power supply voltage and current meet the drill set's requirements.
  • Use suitable connectors, wiring, and insulation to prevent electrical noise and interference.
  • Implement proper noise filtering and decoupling capacitors in the circuit design to ensure reliable operation.
  • Refer to the component's datasheet and application notes for specific guidance on operating the Mini Electric Drill Set component.

    Serial.println("Connecting to WiFi...");
  }
  Serial.println("Connected to WiFi");
  server.begin();
}
void loop() {
  WiFiClient client = server.available();
  if (client) {
    String request = client.readStringUntil('

    if (request.indexOf("/drill/on") != -1) {
      // Turn on the drill
      digitalWrite(DRILL_PIN, HIGH);
      client.println("Drill is on");
    } else if (request.indexOf("/drill/off") != -1) {
      // Turn off the drill
      digitalWrite(DRILL_PIN, LOW);
      client.println("Drill is off");
    }
    client.stop();
  }
}
```

}
void loop() {
  if (bluetooth.available() > 0) {
    char cmd = bluetooth.read();
    if (cmd == '1') {
      // Turn on the drill
      digitalWrite(DRILL_PIN, HIGH);
      Serial.println("Drill is on");
    } else if (cmd == '0') {
      // Turn off the drill
      digitalWrite(DRILL_PIN, LOW);
      Serial.println("Drill is off");
    }
  }
}
```
Note: Connect the Bluetooth module to the Arduino Board and pair it with a smartphone or PC. Send '1' to turn on the drill and '0' to turn off the drill using a serial terminal or a custom mobile app.
