Description
- Stepper motor with a standard interface, when used directly pluggable.?
- A, B, C, D four-phase LED indicates the status of the stepper motor work.
- 5 line 4 phase can be used for ordinary ULN2003 chip driver, connect to the 2 phase, support the development board£¬With convenient use, direct docking
- Drive Module Board Size(in): 1.37*1.18*0.6 ; Stepper Motor diameter: 1.06(in) ; Stepper Motor lines: 9.45(in)
- Great packing in a box: 5 sets Uln2003 Stepper Motor + Driver Board (with a little gift)
Specification
Programm Code Example
The Arduino IDE supports a library for stepper motor after connecting the motor with the microcontroller you can upload the sketch to the microcontroller. The following is the code of an example program, it can be modified according to your needs:
#define IN1 8
#define IN2 9
#define IN3 10
#define IN4 11
int Steps = 0;
boolean Direction = true;
void setup() {
Serial.begin(9600);
pinMode(IN1, OUTPUT);
pinMode(IN2, OUTPUT);
pinMode(IN3, OUTPUT);
pinMode(IN4, OUTPUT);
}
void loop() {
for(int i=0; i<4096; i++){
stepper(1);
delayMicroseconds(800);
}
Direction = !Direction;
}
void stepper(int xw) {
for (int x = 0; x < xw; x++) {
switch (Steps) {
case 0:
digitalWrite(IN1, LOW);
digitalWrite(IN2, LOW);
digitalWrite(IN3, LOW);
digitalWrite(IN4, HIGH);
break;
case 1:
digitalWrite(IN1, LOW);
digitalWrite(IN2, LOW);
digitalWrite(IN3, HIGH);
digitalWrite(IN4, HIGH);
break;
case 2:
