Dimmer switch not working

[nikhilcuiet]

Dimmer switch not working, but test program works well. it connects and receive message from mobile app but bulb brightness not adjusting.

[kakopappa]

sounds like a hardware issue. Can you control the dimmer brightness without SinricPro?

[nikhilcuiet]

ys.

//Libraries
#include <RBDdimmer.h>//https://github.com/RobotDynOfficial/RBDDimmer

//Parameters
const int zeroCrossPin   = 4;
const int acdPin  = 2;
int MIN_POWER   = 0;
int MAX_POWER   = 100;
int POWER_STEP  = 5;

//Variables
int power   = 0;

//Objects
dimmerLamp acd(acdPin,zeroCrossPin);

void setup()
{
//Init Serial USB
Serial.begin(115200);
Serial.println(F("ESP8266 System"));
acd.begin(NORMAL_MODE, OFF);
}

void loop(){
 //testDimmer();
}

void testDimmer()
{
  for(power=MIN_POWER;power<=MAX_POWER;power+=POWER_STEP){
      acd.setPower(power); // setPower(0-100%);
          Serial.print("lampValue -> ");
          Serial.print(acd.getPower());
          Serial.println("%");
      delay(1000);
  }

  for(power=MAX_POWER;power>=MIN_POWER;power-=POWER_STEP){
      acd.setPower(power); // setPower(0-100%);
          Serial.print("lampValue -> ");
          Serial.print(acd.getPower());
          Serial.println("%");
      delay(1000);
  }
}

this works well

Example looks correct.

There’s a tutorial which shows how to use the robodyn dimmer here.

I already gone through that but unable to find error. Kindy find error in code.

Where’s the code?

[nikhilcuiet]

this example not working. Mobile app working with device. Messages are receiving but no action.

[nikhilcuiet]

Kindly provide a solution

[kakopappa]

If you are using ESP8266 you need to use a different pin for PWM. PIN 2 does not support PWM. Tutorial is using ESP32 so PIN 2 works for it.

[nikhilcuiet]

I am aslo using ep32 pin 4 and 2. the sample program works fine but complete program not working.

[sivar2311]

void loop(){
 //testDimmer();
}

Is this just a typo? Otherwise your working sketch would not work either.

this is the code not that

[sivar2311]

this is the code not that

I meant the working sketch you mentioned before.

Note: Please use code-blocks when you post code. Otherwise your code is very hard to read. To do this, enclose the source code with three backticks ``` before and after the code:

your code here

[nikhilcuiet]

I found the issue pin 2 not supported for PWM. Please not publish this kind mistake in a tutorial.

[nikhilcuiet]

My send issue is that this code not ruining in ESP8266. After programming ESP reset automatically and continuously. pins also I have tried different.

[sivar2311]

ESP32: All pins that can act as outputs can be used as PWM pins (GPIOs 34 to 39 can’t generate PWM). Check https://randomnerdtutorials.com/esp32-pinout-reference-gpios/

But keep in mind that gpio 2 is connected to on-board LED, must be left floating or LOW to enter flashing mode

ESP8266 Note the comment from @kakopappa as he wrote: If you are using ESP8266 you need to use a different pin for PWM. PIN 2 does not support PWM. Tutorial is using ESP32 so PIN 2 works for it.
