一、Arduino和uln2003控制28BYJ48 四相五线步进电机 程序： int Pin0 = 8; int Pin1 = 9; int Pin2 = 10; int Pin3 = 11; int _step = 0; boolean dir = true;//正反转 int stepperSpeed = 1;//电机转速,5ms一步 void setup() { pinMode(Pin0, OUTPUT); pinMode(Pin1, OUTPUT); pinMode(Pin2, OUTPUT); pinMode(Pin3, OUTPUT); } void loop() { switch(_step){ case 0: digitalWrite(Pin0, LOW); digitalWrite(Pin1, LOW); digitalWrite(Pin2, LOW); digitalWrite(Pin3, HIGH); break; case 1: digitalWrite(Pin0, LOW); digitalWrite(Pin1, LOW); digitalWrite(Pin2, HIGH); digitalWrite(Pin3, HIGH); break; case 2: digitalWrite(Pin0, LOW); digitalWrite(Pin1, LOW); digitalWrite(Pin2, HIGH); digitalWrite(Pin3, LOW); break; case 3: digitalWrite(Pin0, LOW); digitalWrite(Pin1, HIGH); digitalWrite(Pin2, HIGH); digitalWrite(Pin3, LOW); break; case 4: digitalWrite(Pin0, LOW); digitalWrite(Pin1, HIGH); digitalWrite(Pin2, LOW); digitalWrite(Pin3, LOW); break; case 5: digitalWrite(Pin0, HIGH); digitalWrite(Pin1, HIGH); digitalWrite(Pin2, LOW); digitalWrite(Pin3, LOW); break; case 6: digitalWrite(Pin0, HIGH); digitalWrite(Pin1, LOW); digitalWrite(Pin2, LOW); digitalWrite(Pin3, LOW); break; case 7: digitalWrite(Pin0, HIGH); digitalWrite(Pin1, LOW); digitalWrite(Pin2, LOW); digitalWrite(Pin3, HIGH); break; default: digitalWrite(Pin0, LOW); digitalWrite(Pin1, LOW); digitalWrite(Pin2, LOW); digitalWrite(Pin3, LOW); break; } if(dir){ _step++; }else{ _step--; } if(_step7){ _step=0; } if(_step0){ _step=7; } delay(stepperSpeed); } 二、arduino?和uln2003?控制两台步进电机?正反双向转动的代码 ? //本Arduino案例演示了双向控制28BYJ-48步进电机的方法 //案例使用了 一个ULN2003 板来控制步进电机. // 28BYJ-48电机是四相八拍电机, 一个双极绕组在电机针脚pins 1 3上 另一个双极绕组在电机针脚pins 2 4上 // 步角度为 5.625/64度，工作频率为100pp
