Wiring Connections: 1. Connect the stepper motor to the A4988 driver:Connect the motor coil wires to the A and B outputs on the driver. Connect the stepper motor driver to the Arduino Uno:Connect the STEP pin on the driver to a digital pin on the Arduino (e.g., Pin 2). Connect the DIR pin on the driver to another digital pin on the Arduino (e.g., Pin 3). Connect the ENABLE pin on the driver to a digital pin on the Arduino (e.g., Pin 4). Connect the GND and VMOT pins on the driver to the ground and power supply, respectively. 2. Power the A4988 driver:Connect the GND and +VDD pins on the driver to the ground and power supply, respectively. 3. Connect the Arduino Uno to your computer using a USB cable.
#include <AccelStepper.h> // Define stepper motor connections and other parameters #define STEP_PIN 2 #define DIR_PIN 3 #define ENABLE_PIN 4 AccelStepper stepper(1, STEP_PIN, DIR_PIN); void setup() { // Set up the motor control pins as outputs pinMode(STEP_PIN, OUTPUT); pinMode(DIR_PIN, OUTPUT); pinMode(ENABLE_PIN, OUTPUT);
Important Note: – Make sure to adjust the wiring and pin configurations based on your specific setup. – Ensure that the power supply voltage matches the stepper motor and driver requirements. This is a basic example using the AccelStepper library. Make sure to install the library through the Arduino Library Manager if you haven't already. Feel free to modify the code according to your specific requirements and motor specifications.
