The ECONOMY MEGA is equipped with robust hardware features to support a variety of applications. Below are the key technical details:

The ECONOMY MEGA features a comprehensive pinout to support various peripherals and sensors. Below is a summary of the pin configuration:

The ECONOMY MEGA is easy to use and highly versatile. Follow the steps below to get started:

• Connect the ECONOMY MEGA to your computer using a USB Type-B cable for programming and power.
• Alternatively, use an external power supply (7-12V) via the VIN pin or DC barrel jack.

• Download and install the Arduino IDE from the official Arduino website.
• Open the Arduino IDE and select Tools > Board > Arduino Mega or Mega 2560.
• Select the appropriate COM port under Tools > Port.
• Write or load your program (sketch) in the IDE and click the Upload button to transfer it to the board.

• Use the digital and analog pins to connect sensors, actuators, and other peripherals.
• Ensure that the total current drawn by connected components does not exceed the board's limits (20 mA per pin).

The following example demonstrates how to blink an LED connected to pin 13 of the ECONOMY MEGA.

// This sketch blinks an LED connected to pin 13 of the ECONOMY MEGA.
// The LED will turn on for 1 second, then off for 1 second, repeatedly.

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

void loop() {
  digitalWrite(13, HIGH); // Turn the LED on
  delay(1000);            // Wait for 1 second
  digitalWrite(13, LOW);  // Turn the LED off
  delay(1000);            // Wait for 1 second
}

• Use appropriate resistors when connecting LEDs to prevent damage to the board.
• Avoid exceeding the maximum current rating of the pins to ensure reliable operation.
• Use decoupling capacitors for noise-sensitive applications.

1. The board is not detected by the computer.

   • Ensure the USB cable is properly connected and functional.
   • Install the necessary drivers for the ECONOMY MEGA (available on the Arduino website).
   • Check if the correct COM port is selected in the Arduino IDE.

2. The program does not upload to the board.

   • Verify that the correct board and port are selected in the Arduino IDE.
   • Press the reset button on the board before uploading the program.
   • Ensure no other software is using the same COM port.

3. Connected components are not functioning as expected.

   • Double-check the wiring and connections.
   • Ensure the components are compatible with the ECONOMY MEGA's voltage and current ratings.
   • Test the components individually to rule out hardware issues.

Q: Can I power the ECONOMY MEGA with a battery?
A: Yes, you can use a 9V battery or any power source within the 7-12V range connected to the VIN pin or DC barrel jack.

Q: Is the ECONOMY MEGA compatible with Arduino shields?
A: Yes, the ECONOMY MEGA is compatible with most Arduino shields designed for the Mega 2560.

Q: How do I reset the board?
A: Press the reset button located near the USB connector to restart the board.
