I need help getting this example code to run motors 3 and 4. I have read all over the page and just do not understand how to get it to run 2 motors forward.
Please help.
#include <AFMotor.h>
AF_DCMotor motor(2, MOTOR12_64KHZ); // create motor #2, 64KHz pwm
void setup() {
Serial.begin(9600); // set up Serial library at 9600 bps
Serial.println("Motor test!");
motor.setSpeed(200); // set the speed to 200/255
}
void loop() {
Serial.print("tick");
motor.run(FORWARD); // turn it on going forward
delay(1000);
Serial.print("tock");
motor.run(BACKWARD); // the other way
delay(1000);
Hello,
I have experience using this library. Each motor you want to control needs to have it's own "AF_DCMotor" line to initialize it, and then each motor will need to be controlled individually. Like so:
// you need this so you can use the adafruit motor shield library:
#include <AFMotor.h>
// this created our first motor (called "motor") on port 3 of the motorshield:
AF_DCMotor motor(3, MOTOR12_64KHZ);
// we do it again, this time our second motor will be called "motor2" on port
// 4 of the motorshield:
AF_DCMotor motor2(4, MOTOR12_64KHZ);
// so now we have 2 motors called "motor" and "motor2"
void setup() {
Serial.begin(9600); // set up Serial library at 9600 bps
Serial.println("Motor test!");
// set the speed to 200 of 255 of "motor". Note that 0 is stop,
// 255 is full speed:
motor.setSpeed(200);
// set the speed to 200 of 255 of "motor2":
motor2.setspeed(200);
}
void loop() {
Serial.print("tick");
motor.run(FORWARD); // turn it on going forward
motor2.run(FORWARD); // motor 2 goes forward as well
delay(1000);
Serial.print("tock");
motor.run(BACKWARD); // the other way
motor2.run(BACKWARD); //again for motor 2
delay(1000);
Serial.print("tack");
motor.run(RELEASE); // stopped
motor2.run(RELEASE); // command motor 2 to stop
delay(1000);
}
You can run 4 motors, but you need to give them all different names as well as put them on different ports of the motor shield. Just define them like I did in the above examples. Also there is no reason to name your motors "motor" and "motor2" - they can be anything you want, such as "leftWheel" and "rightWheel" then you can issue commands like this:
//initialize the wheel on port 1, calling it leftWheel:
AF_DCMotor leftWheel(1, MOTOR12_64KHZ);
I remember seeing before the tracks and wheels you are using for your robot but I don't remember where I've seen it - can you tell me where you got the tracks?
