Good evening good people the arduino forum. I have two arduinos set in master and slave mode using two hc-05 chips and the connection between them works as I can succesfully control an LED and RGB LED using the master remote. I know the value is being read but when I try to control servos like I normally do, they shake and rattle at all times. I know the code is very simple and would love advice on what needs to change. please do not just comment see serial examples or something similar
#include <SoftwareSerial.h>
#include <Servo.h>
Servo servo1;
SoftwareSerial BTSerial(10, 11);
//OP LED
const int OP_led = 2;
//RGB LED
const int redPin = 5;
const int greenPin = 6;
const int bluePin = 7;
//Servo Pins
const int servo1_pin = 12;
int initial_position = 90;
int servoIncrement = 10;
void setup()
{
BTSerial.begin(9600);
//Op and RGB
pinMode(redPin, OUTPUT);
pinMode(greenPin, OUTPUT);
pinMode(bluePin, OUTPUT);
pinMode(OP_led, OUTPUT);
digitalWrite(OP_led, LOW);
//Servos
servo1.attach(servo1_pin);
servo1.write(initial_position);
}
void loop()
{
while (BTSerial.available() > 0)
{
char value = BTSerial.read(); // Reads the data from the serial port
if (value == 'q')
{
digitalWrite(OP_led, HIGH); // LED Off
}
else if (value == 'w')
{
digitalWrite(OP_led, LOW); // LED On
}
else if (value == 'e')
{
setColor(0, 0, 0); // none
}
else if (value == 'r')
{
setColor(255, 0, 0); // red
}
else if (value == 't')
{
setColor(0, 255, 0); // blue
}
else if (value == 'y')
{
setColor(0, 0, 255); // green
}
else if (value == 'u')
{
setColor(255, 255, 255); // white
}
else if (value == 'i')
{
setColor(255, 255, 0); // purple
}
else if (value == 'o')
{
servo1.write(0);
delay(100);
}
else if (value == 'p')
{
servo1.write(180);
delay(100);
}
}
}
void setColor(int redValue, int greenValue, int blueValue) {
analogWrite(redPin, redValue);
analogWrite(greenPin, greenValue);
analogWrite(bluePin, blueValue);
}
I have both servos connected to an external 6V battery, the GND from the 6v is connected to the two GNDs from of the servos and the 6V to VCC of Servos, both servo 3rd wire connected to digital pin with pwm on arduino mega
A resistor? Can you show a schematic that includes th servos, battery, resistor and Arduino connections. I don't know what a resistor is doing in the circuit.
So I have tried with a resistor, a capacitor, noting and a piece of wire between the voltage and GND of the battery. The strange thing is when I set the initial position the motors move where I want without a fuss but the moment I turn on the controller the motors start to spasm. However, the master code for the controller is just sending an 'o' or a 'p' which shouldn't be causing all this trouble. Below is the master code and wiring info.
