Paso 4: código
El código puede ser encontrado abajo y necesita un IDE de Arduino modificado trabajar con la Junta LinkIt uno para cargar el código.
Esto es sólo un código de ejemplo que hace el motor girar en direcciones opuestas.
int enA = 10; int in1 = 9; int in2 = 8; // motor two int enB = 5; int in3 = 7; int in4 = 6; void setup() { // set all the motor control pins to outputs pinMode(enA, OUTPUT); pinMode(enB, OUTPUT); pinMode(in1, OUTPUT); pinMode(in2, OUTPUT); pinMode(in3, OUTPUT); pinMode(in4, OUTPUT); } void demoOne() { // this function will run the motors in both directions at a fixed speed // turn on motor A digitalWrite(in1, HIGH); digitalWrite(in2, LOW); // set speed to 200 out of possible range 0~255 analogWrite(enA, 200); // turn on motor B digitalWrite(in3, HIGH); digitalWrite(in4, LOW); // set speed to 200 out of possible range 0~255 analogWrite(enB, 200); delay(2000); // now change motor directions digitalWrite(in1, LOW); digitalWrite(in2, HIGH); digitalWrite(in3, LOW); digitalWrite(in4, HIGH); delay(2000); // now turn off motors digitalWrite(in1, LOW); digitalWrite(in2, LOW); digitalWrite(in3, LOW); digitalWrite(in4, LOW); } void demoTwo() { // this function will run the motors across the range of possible speeds // note that maximum speed is determined by the motor itself and the operating voltage // the PWM values sent by analogWrite() are fractions of the maximum speed possible // by your hardware // turn on motors digitalWrite(in1, LOW); digitalWrite(in2, HIGH); digitalWrite(in3, LOW); digitalWrite(in4, HIGH); // accelerate from zero to maximum speed for (int i = 0; i < 256; i++) { analogWrite(enA, i); analogWrite(enB, i); delay(20); } // decelerate from maximum speed to zero for (int i = 255; i >= 0; --i) { analogWrite(enA, i); analogWrite(enB, i); delay(20); } // now turn off motors digitalWrite(in1, LOW); digitalWrite(in2, LOW); digitalWrite(in3, LOW); digitalWrite(in4, LOW); } void loop() { demoOne(); delay(1000); demoTwo(); delay(1000); }
