Digital Dimmer Module

The board can be used in applications where dimming of 110-220V AC power is required like dimming of bulb or fan. The input can be simple 4 bit high/low signal from microcontroller working at 3V or 5V which is isolated with the use of opto-couplers. Total of 16 levels of power control can be set from totally off(0%) to full on(100%) as per input control levels.

    Dear Sir,

    Please find the corrected code below,

    #include <SoftwareSerial.h>

    SoftwareSerial mySerial(10, 11); // RX, TX


    void setup()
    {
    // Open serial communications and wait for port to open:
    Serial.begin(9600);
    while (!Serial) {
    ; // wait for serial port to connect. Needed for Leonardo only
    }
    Serial.println("Starting Program!");

    //Up all the relays connected serial to the Dimmer
    pinMode(5, OUTPUT);
    pinMode(6, OUTPUT);
    pinMode(7, OUTPUT);
    digitalWrite(5, HIGH);
    digitalWrite(6, HIGH);
    digitalWrite(7, HIGH);

    // set the data rate for the SoftwareSerial port

    mySerial.begin(9600);
    Serial.write('S');
    mySerial.write('S');
    delay(1000);
    }

    void loop() // run over and over
    {
    for(int i=0; i<10; i++) {

    int percentageVal = i* 10;
    CONVERT_DISPLAY('B',percentageVal);
    delay(5*1000);
    }

    delay(2000);
    }


    void CONVERT_DISPLAY(unsigned char val ,unsigned int d)
    {

    unsigned char dig1,dig2,dig3,dig[3];
    unsigned char x;
    unsigned char temp;
    temp=d;
    temp=temp/10;
    dig1=d%10;
    dig2=temp%10;
    dig3=temp/10;

    dig[0]=dig3;
    dig[1]=dig2;
    dig[2]=dig1;

    Serial.write(val);
    mySerial.write(val);
    for(x=0;x<3;x++)
    {
    temp=dig[x]|0x30;
    Serial.write(temp);
    mySerial.write(temp);

    }

    }

    Yes, It works for ceiling fan,but there might be some humming sound in this Digital Dimmer Module.

    FYI, we do have another dimmer Module given in below link, this device will not produce any humming sound since this device have snubber circuit with it.Kindly click below link for more details.

    Dear Sir/Madam,

    Greetings From RDL!!!

    We have already implemented the same concept, kindly click below link for details of the WiFi Dimmer SSR 230V 8A-ESP8266 for your reference. 
    If you still wanted to interface digital dimmer with ESP WiFi Module,you just connect the GPIO5,GPIO4,GPIO15,GPIO13 (IO Pins) of the ESP8266Module to the D0,D1,D2,D3 Digital Pins of the  Digital Dimmer Module respectively, You need to write the code in ESP to make the respective pins High or Low.
    Note: Connect 5V and Gnd Pins the Digital Dimmer Module to the 5V Supply. Provide the 3.3V Supply to the ESP8266 Module.

    A:

    Just provide 5V and GND to respective pins of the module. then its just the i/o connections. you can know which i/o pins you could connect by looking at the sample code provided.
