手持脫機(jī)步進(jìn)電機(jī)控制器
簡(jiǎn)介: 不知道各位小伙伴們常不常用步進(jìn)電機(jī),因其精確的控制性很容易實(shí)現(xiàn)步進(jìn)電機(jī)的角度和速度控制,然而也因?yàn)榇颂匦詫?dǎo)致在前期對(duì)步進(jìn)電機(jī)調(diào)試時(shí)比較繁瑣;所以結(jié)合arduino nano和A4988,我們開源一款方便測(cè)試步進(jìn)電機(jī),同時(shí)又可燒寫不同程序?qū)崿F(xiàn)移植復(fù)用的手持脫機(jī)步進(jìn)電機(jī)控制器。

int Menpin=8;
int i=200;
int BUTTON1 = A2;

char key;
void setup()

pinMode(Msteppin,OUTPUT);//驅(qū)動(dòng)
pinMode(Mdirpin,OUTPUT);//方向
pinMode(Menpin,OUTPUT);//使能
digitalWrite(Menpin,LOW);
pinMode(A2,INPUT_PULLUP);//A2上拉
pinMode(A3,INPUT_PULLUP);//A3上拉
Serial.begin(9600);
}
void a()
{digitalWrite(Mdirpin,HIGH);
int i=0;
while(i<200)
