Toy elevator

给小朋友做的一个电梯玩具。需要用到

28byj-48 step motor

Arduino board

string

connection wires

2 buttons

code

#include <Stepper.h>

 

const int buttonPin2 = 2;

// Initialize the Stepper library with the pins connected to the ULN2003 driver

Stepper stepper(stepsPerRevolution, 8, 10, 9, 11);  // IN1, IN2, IN3, IN4

 

void setup() {

  // Set the motor speed (in RPM)

  stepper.setSpeed(65);  // Adjust the speed, 15 RPM is a good starting point
