Code Examples
### Example 1: Controlling a Stepper Motor
In this example, we'll demonstrate how to control a stepper motor using the Ramps 1.4 Shield and the A4988 stepper motor driver.
```cpp
// Include the necessary libraries
#include <Arduino.h>
#include <AccelStepper.h>
// Define the stepper motor pins
#define STEP_PIN 2
#define DIR_PIN 3
#define ENABLE_PIN 4
// Create an instance of the AccelStepper library
AccelStepper stepper(AccelStepper::DRIVER, STEP_PIN, DIR_PIN);
void setup() {
// Initialize the stepper motor
stepper.setEnablePin(ENABLE_PIN);
stepper.disable();
delay(100);
stepper.enable();
}
void loop() {
// Move the stepper motor 100 steps forward
stepper.moveTo(100);
while (stepper.currentPosition() != 100) {
stepper.run();
delay(10);
}
delay(1000);
// Move the stepper motor 100 steps backward
stepper.moveTo(-100);
while (stepper.currentPosition() != -100) {
stepper.run();
delay(10);
}
delay(1000);
}
```
### Example 2: Controlling a Heater and Fan
In this example, we'll demonstrate how to control a heater and fan using the Ramps 1.4 Shield's MOSFET switching circuits.
```cpp
// Define the heater and fan pins
#define HEATER_PIN 7
#define FAN_PIN 6
void setup() {
// Initialize the heater and fan pins as outputs
pinMode(HEATER_PIN, OUTPUT);
pinMode(FAN_PIN, OUTPUT);
}
void loop() {
// Turn on the heater
digitalWrite(HEATER_PIN, HIGH);
delay(5000);
// Turn off the heater and turn on the fan
digitalWrite(HEATER_PIN, LOW);
digitalWrite(FAN_PIN, HIGH);
delay(5000);
// Turn off the fan
digitalWrite(FAN_PIN, LOW);
delay(5000);
}
```
### Example 3: Reading the SD Card
In this example, we'll demonstrate how to read a G-code file from the micro-SD card using the Ramps 1.4 Shield's SD card slot.
```cpp
#include <SD.h>
// Define the SD card pin
#define SD_PIN 53
void setup() {
// Initialize the SD card
pinMode(SD_PIN, OUTPUT);
SD.begin(SD_PIN);
}
void loop() {
// Open the G-code file
File file = SD.open("example.gcode");
if (file) {
// Read the file line by line
while (file.available()) {
String line = file.readStringUntil('
');
Serial.println(line);
}
file.close();
} else {
Serial.println("Failed to open file");
}
delay(1000);
}
```
