Hello everyone,
I'm build hexapod robot with 12 servos (rob 10333 medium) from spearkfun, arduino and pololu driver
i connected the driver to two servo and then to the arduino
the driver started to give me error (red led turn on)
so i tried this code:
#include <SoftwareSerial.h>
const int DEFAULT_BAUD = 9600;
const int SERVO_CONTROLLER_RX_PIN = 11; // The SERVO CONTROLLER'S RX PIN.
const int SERVO_CONTROLLER_TX_PIN = 12; // The SERVO CONTROLLER'S TX PIN.
SoftwareSerial ServoController = SoftwareSerial(SERVO_CONTROLLER_RX_PIN, SERVO_CONTROLLER_TX_PIN);
void setup()
{
ServoController.begin(DEFAULT_BAUD);
delay(500);
}
void moveServo(int ServoChannel, int target)
{
//656ms PWM pulse represents a servo angle of 0 degrees.
//2000ms PWM pulse represents a servo angele of 180 degrees.
//These values could vary based on the servo you use, check your servo's
//spec documentation and verify what PWM pulses are needed to move it.
byte serialBytes[4]; //Create the byte array object that will hold the communication packet.
target = (map(target, 0, 180, 656, 2000) * 4); //Map the target angle to the corresponding PWM pulse.
serialBytes[0] = 0x84; // Command byte: Set Target.
serialBytes[1] = ServoChannel; // First byte holds channel number.
serialBytes[2] = target & 0x7F; // Second byte holds the lower 7 bits of target.
serialBytes[3] = (target >> 7) & 0x7F; // Third byte holds the bits 7-13 of target.
ServoController.write(serialBytes, sizeof(serialBytes)); //Write the byte array to the serial port.
}
void loop()
{
moveServo(0, 0); //Move the servo on channel 0 to an angle of 0 degrees
delay(2000); //Wait 2000ms
moveServo(0,45);//Move the servo on channel 0 to an angle of 45 degrees
delay(2000);
moveServo(0,0); //Move the servo on channel 0 to an angle of 0 degrees
delay(2000); //Wait 2000ms
}
still the one servo doesn't move proper, knowing that i powered the driver to power the servo from the arduino 5V
what should i do ???
