Help wiring and programming a Robot Arm? Answered

That is what I was thinking. Did I wire it correctly for the power?

Looks OK

I have it wired up now and when I turn it on it just seizures.

Take off all but one servo, get that running. I'm not pretending to read the "drawing" of what you have. I might read a circuit diagram.

What code have you loaded on the Arduino ?

#include

Servo myservo;
Servo myservo2;
Servo myservo3;
Servo myservo4;
Servo myservo5;

int potpin = 1;
int potpin2 = 2;
int potpin3 = 3;
int potpin4 = 4;
int potpin5 = 5;
int val;
int val2;
int val3;
int val4;
int val5;

void setup()
{
myservo.attach(1);
myservo2.attach(2);
myservo3.attach(3);
myservo4.attach(4);
myservo5.attach(5);
}

void loop()
{
val = analogRead(potpin);
val2 = analogRead(potpin2);
val3 = analogRead(potpin3);
val4 = analogRead(potpin4);
val5 = analogRead(potpin5);
val = map(val, 0, 1023, 0, 179);
val2 = map(val, 0, 1023, 0, 179);
val3 = map(val, 0, 1023, 0, 179);
val4 = map(val, 0, 1023, 0, 179);
val5 = map(val, 0, 1023, 0, 179);
myservo.write(val);
myservo2.write(val2);
myservo3.write(val3);
myservo4.write(val4);
myservo5.write(val5);

delay(15);
}

Your code around the map statements is wrong - but this is cleaner anyway:

myservo.write( map( analogRead (potpin),0,1023,0,178));
myservo2.write( map( analogRead (potpin2),0,1023,0,178));
myservo3.write( map( analogRead (potpin3),0,1023,0,178));
//saves variables and code.

Ok I tried this:

Servo myservo;
Servo myservo2;
Servo myservo3;
Servo myservo4;
Servo myservo5;

int potpin = 1;
int potpin2 = 2;
int potpin3 = 3;
int potpin4 = 4;
int potpin5 = 5;
int val;
int val2;
int val3;
int val4;
int val5;

void setup()
{
myservo.attach(1);
myservo2.attach(2);
myservo3.attach(3);
myservo4.attach(4);
myservo5.attach(5);
}

void loop()
{
val = analogRead(potpin);
val2 = analogRead(potpin2);
val3 = analogRead(potpin3);
val4 = analogRead(potpin4);
val5 = analogRead(potpin5);
val = map(val, 0, 1023, 0, 179);
val2 = map(val, 0, 1023, 0, 179);
val3 = map(val, 0, 1023, 0, 179);
val4 = map(val, 0, 1023, 0, 179);
val5 = map(val, 0, 1023, 0, 179);
myservo.write( map( analogRead (potpin),0,1023,0,178));
myservo2.write( map( analogRead (potpin2),0,1023,0,178));
myservo3.write( map( analogRead (potpin3),0,1023,0,178));
//saves variables and code.

delay(15);
}

But I got this:

//saves variables and code.delay(15);
}

Ok this works. I have control and everything is responding. However It has a severe twitching problem.

Well the servo knob example is only for one servo. I tried modifying and all it does it seizures.

What do you mean by "seizures" ? Do you mean "seizes up", ie, twiddling the pots does nothing?

Are you getting a change in volts on the input to the Arduino AnalogIn pins ?

The bot is apparently only taking input from the A1 pot, and assigning that to all of the servos.

debug it a bit, take it down to just 2 servos, add some Serial.print's to verify the data before it hits the servo objects

Try moving the servo pins up past 0 and 1 (these are usually used by serial communication)

so have them start at 2 or so
