Easy pump with Arduino and Stepper motor.https://youtu.be/dSlVYtNwtloI use: 6x bearings: 10x5x4 mm NEMA 17 Stepper motor with 5mm shaft stepper driver Pololu A4988 Arduino Nano resistor 10k switch silicone pipe 5x3mm some screws M3, M2 and nuts. Arduino code: int x; const int buttonPin = 2; int buttonState = 0; void setup(){ pinMode(6, OUTPUT); // Enable pinMode(5, OUTPUT); // Stepping pinMode(4, OUTPUT); // Dir 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); // Set Enable low digitalWrite(4, HIGH); // Set Dir high for (x = 0; x <100; x++) { digitalWrite(5, HIGH); // Output high delayMicroseconds(300); // Wait 1/2 a ms digitalWrite(5, LOW); // Output low delayMicroseconds(300); // Wait 1/2 a ms} delay(1000); // pause one second } else { digitalWrite(6, HIGH); // Set Enable high } }
