MPU 6050 problem SOLVED

hi, I'm trying to use the mpu6050 to move the servo and the led, but how should I set if(ax == 17000 or angle 180) so that it turns (rgb led)red, how should I do it? thank you

[code]

#include <FastLED.h>



#define NUM_LEDS 1
CRGB leds[NUM_LEDS];
#include <Wire.h>

#include <MPU6050.h>

#include <Servo.h>   

Servo sg90;          

int servo_pin = 2;

MPU6050 sensor ;

int16_t ax, ay, az ;

int16_t gx, gy, gz ;
int pos = 90;    // variable to store the servo position
int lastPos = 90;
void setup ( )

{ 
FastLED.addLeds<WS2812, 6>(leds, NUM_LEDS);
sg90.attach ( servo_pin );
Serial.begin(9600);
Wire.begin ( );



sensor.initialize ( ); 



}




void loop ( ) 

{ 

sensor.getMotion6 (&ax, &ay, &az, &gx, &gy, &gz);
ax = map (ax, -17000, 17000, 0, 180) ;
if(ax <= -4700)
{
    leds[1] = CRGB(255,0,0);
    Serial.print("YES");
}
else
{
    leds[1] = CRGB(0,0,0);
    Serial.print("NO");
}


sg90.write (ax); 


delay (20);

}

Please follow the advice given in the link below when posting code, in particular the section entitled 'Posting code and common code problems'

Use code tags (the </> icon above the compose window) to make it easier to read and copy for examination

I'm trying to put the code in the code tags, but it doesn't work

5

In the post editor, select the code and push the "</>" editor button.

it works now

7

but what about the code, how to solve it? Thank you

I'm the one who solved it, I had to use degrees

Hi,

Can you please post your working code to help close this thread and for others who may have a similar problem.

Thanks.. Tom... :smiley: :+1: :coffee: :australia:
