Arduino MEGA 2560 R3 Compatible Board DocumentationOverviewThe Arduino MEGA 2560 R3 compatible board is a microcontroller board based on the ATmega2560 microchip. It is a popular choice for various IoT and robotics projects due to its ability to connect a large number of sensors, actuators, and peripherals. This board is a cost-effective alternative to the original Arduino MEGA 2560 R3 board, offering identical functionality and compatibility.Technical SpecificationsMicrocontroller: ATmega2560
Operating Voltage: 5V
Input Voltage: 7-12V
Digital I/O Pins: 54 (of which 15 can be used as PWM outputs)
Analog Input Pins: 16
Flash Memory: 256 KB
SRAM: 8 KB
EEPROM: 4 KB
Clock Speed: 16 MHzCode Examples### Example 1: Reading Analog Sensor DataThis example demonstrates how to read analog sensor data using the Arduino MEGA 2560 R3 compatible board.
```c++
const int sensorPin = A0; // Pin connected to analog sensorvoid setup() {
Serial.begin(9600);
}void loop() {
int sensorValue = analogRead(sensorPin);
float voltage = sensorValue (5.0 / 1023.0);
Serial.print("Sensor Value: ");
Serial.print(sensorValue);
Serial.print(" | Voltage: ");
Serial.print(voltage);
Serial.println(" V");
delay(1000);
}
```
In this example, we connect an analog sensor to pin A0 of the board. The `analogRead()` function is used to read the sensor value, which is then converted to a voltage value using the formula `voltage = (sensorValue 5.0) / 1023.0`. The resulting values are printed to the serial monitor.### Example 2: Controlling LEDs with Digital OutputsThis example demonstrates how to control LEDs using the digital outputs of the Arduino MEGA 2560 R3 compatible board.
```c++
const int ledPins[] = {2, 3, 4}; // Pins connected to LEDsvoid setup() {
for (int i = 0; i < 3; i++) {
pinMode(ledPins[i], OUTPUT);
}
}void loop() {
for (int i = 0; i < 3; i++) {
digitalWrite(ledPins[i], HIGH);
delay(500);
digitalWrite(ledPins[i], LOW);
delay(500);
}
}
```
In this example, we connect three LEDs to digital pins 2, 3, and 4 of the board. In the `setup()` function, we set these pins as outputs using the `pinMode()` function. In the `loop()` function, we use a `for` loop to iterate through the array of led pins, turning each LED on and off with a 500ms delay using the `digitalWrite()` function.Additional ResourcesArduino MEGA 2560 R3 compatible board datasheet
