Hi,Ii am trying to build a robot that will scramble a rubix cube, at the moment, I am setting up procedures for each action then executing them in the main loop with delays betewen just to test everything, the stepper sections of coder are working fine, however when I added the servos, i got an error message when I compiled saying
"“exit status 1
request for member ‘attach’ in ‘up’, which is of non-class type ‘Servo()’”
i have posted my code below
//Include the Arduino Stepper Library
#include <Stepper.h>
#include <Servo.h>
// Define Constants
Servo up();
Servo pinch();
// Number of steps per internal motor revolution
const float STEPS_PER_REV = 32;
// Amount of Gear Reduction
const float GEAR_RED = 64;
// Number of steps per geared output rotation
const float STEPS_PER_OUT_REV = STEPS_PER_REV * GEAR_RED;
// Define Variables
// Number of Steps Required
int StepsRequired;
// Create Instance of Stepper Class
// Specify Pins used for motor coils
// The pins used are 8,9,10,11
// Connected to ULN2003 Motor Driver In1, In2, In3, In4
// Pins entered in sequence 1-3-2-4 for proper step sequencing
Stepper steppermotor(STEPS_PER_REV, 8, 10, 9, 11);
void setup()
{
up.attach(5); //sets lifting servo control to pin 5
pinch.attach(3); //sets pinching servo control to pin 5
//(Stepper Library sets pins as outputs)
}
void loop()
{
clock();
delay(1000);
clock2();
delay(1000);
aclock();
delay(1000);
aclock2();
open();
delay(1000);
close();
delay(1000);
lift();
delay(1000);
drop();
}
void clock() // Clockwise 1/4 turn
{
StepsRequired = STEPS_PER_OUT_REV / 4;
steppermotor.setSpeed(700);
steppermotor.step(StepsRequired);
}
void clock2() // Clockwise 1/2 turn
{
StepsRequired = STEPS_PER_OUT_REV / 2;
steppermotor.setSpeed(700);
steppermotor.step(StepsRequired);
}
void aclock() // Anti-Clockwise 1/4 turn
{
StepsRequired = - STEPS_PER_OUT_REV / 4;
steppermotor.setSpeed(700);
steppermotor.step(StepsRequired);
}
void aclock2() // Anti-Clockwise 1/2 turn
{
StepsRequired = - STEPS_PER_OUT_REV / 2;
steppermotor.setSpeed(700);
steppermotor.step(StepsRequired);
}
void open() //Squeeze jaws
{
pinch.write(180);
}
void close() //Release jaws
{
pinch.write(0);
}
void lift() //Lift jaws
{
up.write(180);
}
void drop() //Drop jaws
{
up.write(0);
