Hello,

I didn’t manage to dot it whith a WS2812B RGB led strip.

The strip keeps lighted.

I used the following code :

#include
#define NUM_LEDS 3
#define LED_PIN 4
#define COLOR_ORDER GRB
#define LED_TYPE WS2812B
#define BRIGHTNESS 30
#define MIC 0

CRGB leds[NUM_LEDS];

void setup() {
FastLED.addLeds(leds, NUM_LEDS);
FastLED.setBrightness( BRIGHTNESS );
Serial.begin(9600);

//here is an input for sound sensor
pinMode(MIC, INPUT);

//here we are setting up all pins as an outputs for LEDs
for(int z = 0; z < 10; z++){
pinMode(z, OUTPUT);
}
}

void loop() {

//here we are storing the volume value
int volume = analogRead(A0);
Serial.println (volume);

//max value for analog read is 1023 but it must be very very loud to reach this value
//so I lower it down in map function to 700
//mapping volume value to make it easier to turn LEDs on
volume = map(volume, 0, 700, 0, 10);

//for loop to turn on or off all LEDs
//thanks to this loop code for this project is very short
//we are going through all pins where we have LEDs and checking if the volume is
//bigger then pin number (that's why we are maping the volume)
for(int a = 0; a = a)
{
//if it is bigger we can turn on the LED
leds[a]= CRGB::Green;
FastLED.show();
}

else{
//if it is smaller we can turn the LED off
leds[a]= CRGB::Black;
FastLED.show();
}
}
}

Cann you help me ??

Thank you

thank you!

Here is how you do it: https://playground.arduino.cc/Learning/9VBatteryAdapter

In my opinion this is not yet possible.
