样例代码
//This motor shield use Pin 6,9,7,4 to control the motor // Simply connect your motors to M1+,M1-,M2+,M2- // Upload the code to Arduino/Roboduino // Through serial monitor, type 'a','s', 'w','d','x' to control the motor int EN1 = 6; int EN2 = 9; //Roboduino Motor shield uses Pin 9 int IN1 = 7; int IN2 = 4; //Latest version use pin 4 instead of pin 8 void Motor1(int pwm, boolean reverse) { analogWrite(EN1,pwm); //set pwm control, 0 for stop, and 255 for maximum speed if(reverse) { digitalWrite(IN1,HIGH); } else { digitalWrite(IN1,LOW); } } void Motor2(int pwm, boolean reverse) { analogWrite(EN2,pwm); if(reverse) { digitalWrite(IN2,HIGH); } else { digitalWrite(IN2,LOW); } } void setup() { int i; for(i=4;i<=7;i++) //For Arduino Motor Shield pinMode(i, OUTPUT); //set pin 4,5,6,7 to output mode Serial.begin(9600); } void loop() { int x,delay_en; char val; while(1) { val = Serial.read(); if(val!=-1) { switch(val) { case 'w'://Move ahead Motor1(100,true); //You can change the speed, such as Motor(50,true) Motor2(100,true); break; case 'x'://move back Motor1(100,false); Motor2(100,false); break; case 'a'://turn left Motor1(100,false); Motor2(100,true); break; case 'd'://turn right Motor1(100,true); Motor2(100,false); break; case 's'://stop Motor1(0,false); Motor2(0,false); break; } } } }
