Can we control minimum voltage to maximum voltage using arduino

Hello every one I have a question here. Can we control minimum voltage to maximum voltage using arduino?

Sure, I can use an Arduino to control minimum and maximum voltage. I do not know of your coding and electronic skills to give you an honest answer to weather you can do it. What I suggest is that you give it a try and your own success or failure will let you know if you can do it.

#include <FastLED.h>

#define LED_PIN     7
#define NUM_LEDS    20


const int DUTY = 64;
void setup() {

  FastLED.addLeds<WS2812, LED_PIN, GRB>(leds, NUM_LEDS);

}

void loop() {

  for (int i = 0; i <= 19; i++) {
    leds[i] = CRGB ( 0, 0, 255);
    FastLED.show();
    delay(40);
  }
  for (int i = 19; i >= 0; i--) {
    leds[i] = CRGB ( 255, 0, 0);
    FastLED.show();
    delay(40);
  }
}

Can anyone rectify this error

did you install the fast led library? Did you try the example code?

The posted code does not show the Arduino being used as a voltage controller.

7

What this problem has to do with your initial question?

8

here is some instructions that I am not sue if you will be able to follow, with me being unfamiliar with your ability to follow instructions, that you may find helpful on installing fastled.

GitHub - stnkl/FastLEDHub: Control multiple FastLED lightstrip animations on the ESP8266 and ESP32 without reuploading.

Thanks, I tried this library still I'm getting this error.

 #include <FastLEDHub.h>

So you need to install the FastLEDHub.h library too.

Please read and TRY TO UNDERSTAND the error messages yourself.

11

Did you install the library?

12

Yes, I have install the library

led

13

Did you install the library to Arduino/libraries/FastLEDHub-master/FastLEDHub-master? The library should be in Arduino/libraries/FastLEDHub.

I am sure you did not follow this instruction

I have send library path and error

16 
#include <FastLEDHub.h>

#define LED_PIN     7
#define NUM_LEDS    20


const int DUTY = 64;
void setup() {

  FastLED.addLeds<WS2812, LED_PIN, GRB>(leds, NUM_LEDS);

}

void loop() {

  for (int i = 0; i <= 19; i++) {
    leds[i] = CRGB ( 0, 0, 255);
    FastLED.show();
    delay(40);
  }
  for (int i = 19; i >= 0; i--) {
    leds[i] = CRGB ( 255, 0, 0);
    FastLED.show();
    delay(40);
  }
}

Why not put the library into
C:\Users\DELL\Documents\Arduino\libraries\FastLEDHub\ where it belongs?

do you see the difference between

C:\Users\DELL\Documents\Arduino\libraries\FastLEDHub\FastLEDHub

and

C:\Users\DELL\Documents\Arduino\libraries\FastLEDHub

?

18

And also can you chek the code again?

19

Why did you created TWO directories

enclosed one in another?

20

I did not create 2 directories. I am trying to let the OP know they created 2 directories but the OP keeps missing the clue.
