Easydriver Board Drive Step Motor Kit

Description

EasyDriver stepper motor drive is easy to use, can work with any Pulse signal equipment which output is 0-5V (3V please Short circuit SJ2) . Kit include： 1pcs Easydriver board 1pcs 142 hybrid 2 phase 4-wire stepper motor 1pcs middle breadboard 10pcs jumper wires CODE#define DIR_PIN 2 #define STEP_PIN 3void setup() { pinMode(DIR_PIN, OUTPUT); pinMode(STEP_PIN, OUTPUT); }void loop(){ //rotate a specific number of degrees rotateDeg(360, 1); delay(1000); rotateDeg(-360, .1); //reverse delay(1000); //rotate a specific number of microsteps (8 microsteps per step) //a 200 step stepper would take 1600 micro steps for one full revolution rotate(1600, .5); delay(1000); rotate(-1600, .25); //reverse delay(1000); }void rotate(int steps, float speed){ //rotate a specific number of microsteps (8 microsteps per step) - (negitive for reverse movement) //speed is any number from .01 -> 1 with 1 being fastest - Slower is stronger int dir = (steps > 0)?
