1. Powering the Board: Connect a power supply to the Vin and GND pins, ensuring that the voltage is within the recommended limits.
2. Connecting I/O Devices: Attach sensors, actuators, or other components to the digital and analog pins as required for your project.
3. Programming the Board: Use the Arduino IDE or other compatible software to write and upload code to the MakerEdu Creator.
4. Monitoring and Debugging: Utilize the serial monitor feature in the Arduino IDE to debug and monitor the output of your program.

• Always disconnect the board from power sources before making or altering connections.
• Observe proper polarity for power connections to prevent damage.
• Avoid drawing more current than the specified limits for each pin.
• Use external power sources when connecting components that require more current than the board can provide.

• Board Not Recognized: Ensure drivers are installed and the USB cable is functioning.
• Sketch Not Uploading: Check the correct board and port are selected in the IDE.
• Unexpected Behavior: Verify wiring, power supply, and code logic.

• Reset the Board: Press the reset button to restart the microcontroller.
• Check Connections: Loose or incorrect connections are often the cause of issues.
• Isolate the Problem: Simplify the circuit and code to isolate the issue.

• Q: Can I power the MakerEdu Creator with a 9V battery?

  • A: Yes, you can use a 9V battery connected to the Vin and GND pins.

• Q: What should I do if I exceed the current limit on a pin?

  • A: Reduce the load immediately to prevent damage and consider using external power sources with transistors or relays to control high-power devices.

• Q: How do I connect the MakerEdu Creator to a computer?

  • A: Use a USB cable to connect the board to a computer for programming and power.

// Blink an LED connected to pin 13

void setup() {
  pinMode(13, OUTPUT); // Set pin 13 as an output
}

void loop() {
  digitalWrite(13, HIGH);   // Turn the LED on
  delay(1000);              // Wait for a second
  digitalWrite(13, LOW);    // Turn the LED off
  delay(1000);              // Wait for a second
}

Note: The example code provided is for illustrative purposes. The actual implementation may vary depending on the specific version of the MakerEdu Creator board and the project requirements.
