Easy DIY Project with Arduino and Stepper Motor. I'm using the following components: * 6x bearings: 10x5x4 mm * NEMA 17 Stepper motor with 5mm shaft * Pololu A4988 stepper driver * Arduino Nano * Resistor 10k * Switch * Silicone pipe 5x3mm * Screws M3, M2 and nuts Here is the Arduino code: ```cpp int x; const int buttonPin = 2; int buttonState = 0; void setup() { pinMode(6, OUTPUT); // Enable the motor pinMode(5, OUTPUT); // Step pin pinMode(4, OUTPUT); // Direction pin digitalWrite(6, LOW); // Set Enable low pinMode(buttonPin, INPUT); Serial.begin(9600); } void loop() { buttonState = digitalRead(buttonPin); Serial.println(buttonState); if (buttonState == HIGH) { digitalWrite(6, LOW); // Disable the motor digitalWrite(4, HIGH); // Set direction high for (x = 0; x < 4000; x++) // Loop 200 times { digitalWrite(5, HIGH); // Output high delayMicroseconds(300); // Wait half a millisecond digitalWrite(5, LOW); // Output low delayMicroseconds(300); // Wait half a millisecond } delay(1000); // Pause for one second } else { digitalWrite(6, HIGH); // Enable the motor } } ```
