Hi, I’m new to Arduino and I am building a moving head with a rgb light inside it. I find two codes; one for the light an another for the servo’s. I want to combine them. I tried lots of ways but it doesn’t work. Please help me 
. This is the code I wrote:
#include <Servo.h>
int potPin = 3; // Potentiometer output connected to analog pin 3
int potVal = 0; // Variable to store the input from the potentiometer
int potPin2 = 0;
int potVal2 = 0;
int potPin3 = 0;
int potVal3 = 0;
// OUTPUT: Use digital pins 9-11, the Pulse-width Modulation (PWM) pins
// LED's cathodes should be connected to digital GND
int redPin = 9; // Red LED, connected to digital pin 9
int grnPin = 10; // Green LED, connected to digital pin 10
int bluPin = 11; // Blue LED, connected to digital pin 11
// Program variables
int redVal = 0; // Variables to store the values to send to the pins
int grnVal = 0;
int bluVal = 0;
Servo myservo;
Servo myservo2;
void setup()
{
pinMode(redPin, OUTPUT); // sets the pins as output
pinMode(grnPin, OUTPUT);
pinMode(bluPin, OUTPUT);
myservo.attach(8);
myservo.attach(7);
}
void loop()
{
{
potVal = analogRead(potPin); // read the potentiometer value at the input pin
if (potVal < 341) // Lowest third of the potentiometer's range (0-340)
{
potVal = (potVal * 3) / 4; // Normalize to 0-255
redVal = 256 - potVal; // Red from full to off
grnVal = potVal; // Green from off to full
bluVal = 1; // Blue off
}
else if (potVal < 682) // Middle third of potentiometer's range (341-681)
{
potVal = ( (potVal-341) * 3) / 4; // Normalize to 0-255
redVal = 1; // Red off
grnVal = 256 - potVal; // Green from full to off
bluVal = potVal; // Blue from off to full
}
else // Upper third of potentiometer"s range (682-1023)
{
potVal = ( (potVal-683) * 3) / 4; // Normalize to 0-255
redVal = potVal; // Red from off to full
grnVal = 1; // Green off
bluVal = 256 - potVal; // Blue from full to off
}
analogWrite(redPin, redVal); // Write values to LED pins
analogWrite(grnPin, grnVal);
analogWrite(bluPin, bluVal);
}
{
potVal2 = analogRead(potPin2);
potVal2 = map (potVal2, 0, 766, 0, 180);
myservo.write(potVal2);
potVal3 = analogRead(potPin3);
potVal3 = map(potVal3 , 0, 766, 90, 180);
myservo2.write(potVal3);
delay(150);
}
}
This is the code I use for my RGB LED:
/*
* Code for making one potentiometer control 3 LEDs, red, grn and blu, or one tri-color LED
* The program cross-fades from red to grn, grn to blu, and blu to red
* Clay Shirky <clay.shirky@nyu.edu>
*/
// INPUT: Potentiometer should be connected to 5V and GND
int potPin = 3; // Potentiometer output connected to analog pin 3
int potVal = 0; // Variable to store the input from the potentiometer
// OUTPUT: Use digital pins 9-11, the Pulse-width Modulation (PWM) pins
// LED's cathodes should be connected to digital GND
int redPin = 9; // Red LED, connected to digital pin 9
int grnPin = 10; // Green LED, connected to digital pin 10
int bluPin = 11; // Blue LED, connected to digital pin 11
// Program variables
int redVal = 0; // Variables to store the values to send to the pins
int grnVal = 0;
int bluVal = 0;
void setup()
{
pinMode(redPin, OUTPUT); // sets the pins as output
pinMode(grnPin, OUTPUT);
pinMode(bluPin, OUTPUT);
}
// Main program
void loop()
{
potVal = analogRead(potPin); // read the potentiometer value at the input pin
if (potVal < 341) // Lowest third of the potentiometer's range (0-340)
{
potVal = (potVal * 3) / 4; // Normalize to 0-255
redVal = 256 - potVal; // Red from full to off
grnVal = potVal; // Green from off to full
bluVal = 1; // Blue off
}
else if (potVal < 682) // Middle third of potentiometer's range (341-681)
{
potVal = ( (potVal-341) * 3) / 4; // Normalize to 0-255
redVal = 1; // Red off
grnVal = 256 - potVal; // Green from full to off
bluVal = potVal; // Blue from off to full
}
else // Upper third of potentiometer"s range (682-1023)
{
potVal = ( (potVal-683) * 3) / 4; // Normalize to 0-255
redVal = potVal; // Red from off to full
grnVal = 1; // Green off
bluVal = 256 - potVal; // Blue from full to off
}
analogWrite(redPin, redVal); // Write values to LED pins
analogWrite(grnPin, grnVal);
analogWrite(bluPin, bluVal);
}
This is the code I use for my servo:
#include <Servo.h>
Servo myservo;
int potpin = 0;
int val;
Servo myservo2;
int potpin2 = 1;
int val2;
void setup()
{
myservo.attach(9);
myservo2.attach(8);
}
void loop()
{
val = analogRead(potpin);
val = map(val, 0, 766, 0, 180);
myservo.write(val);
val2 = analogRead(potpin2);
val2 = map(val2 , 0, 766, 90, 180);
myservo2.write(val2);
delay(150);
}
PLEASE COULD SOMEBODY HELP ME?
