Controling the brightness of a lamp

shramik_salgaonkar · March 11, 2020, 5:49pm

change it to 'Serial`

Bruno_Pedro · April 7, 2020, 8:33pm

Hello,
I hope everyone is okay, because of this pandemic situation.
After i implemented the suggestions you gave me, i uploaded the code sucessufuly to ESP8266, but in cayenne platform it says the ESP8266 is pending connection.
How can I solve this?

#include <RBDdimmer.h>
#include <CayenneMQTTESP8266.h>

// This example shows how to connect to Cayenne using an ESP8266 and send/receive sample data.
// Make sure you install the ESP8266 Board Package via the Arduino IDE Board Manager and select the correct ESP8266 board before compiling.

#define CAYENNE_PRINT Serial
//#define CAYENNE_DEBUG

// WiFi network info.
char ssid = “”;
char wifiPassword = “”;

// Cayenne authentication info. This should be obtained from the Cayenne Dashboard.
char username = “”;
char password = “”;
char clientID = “”;

unsigned long lastMillis = 0;

what do you get in the serial monitor? add this in the code #define CAYENNE_DEBUG

I’m using ESP8266 - CP2102, so I’m trying use: USE_SERIAL.begin(74880);

shramik_salgaonkar · April 9, 2020, 3:34pm

it looks like your esp is reset due to some error. it maybe because of the RBDimmer library. Can you try the basic cayenne esp8266 code.

Bruno_Pedro · April 9, 2020, 3:50pm

I have other projects where I use the ESP8266 connected to motion sensors, luminosity sensors, digital relay and It works with cayenne. Is that what you asking?

shramik_salgaonkar · April 9, 2020, 3:51pm

i am saying it maybe the RBDtimmer library that might be causing the issue.

Bruno_Pedro · April 9, 2020, 3:55pm

So, what you suggest? I remove the library?

shramik_salgaonkar · April 9, 2020, 4:03pm

first, try to check if RBDTimmer library works standalone.

i tried the code with my nodemcu and same result. what are using the library for?

Bruno_Pedro · April 9, 2020, 4:44pm

I’m just using the code you suggested.
What changes should I do?

I just want to use this dimmer: https://robotdyn.com/ac-light-dimmer-module-1-channel-3-3v-5v-logic-ac-50-60hz-220v-110v.html
With ESP8266 - CP2102 NodeMCU V3 Lua, trough a slider widget on cayenne platform to control the brightness/intensity of a lamp.

shramik_salgaonkar · April 9, 2020, 5:08pm

there is nothing i can do if the librray is not supported. Try searching for similer library and see if their compatiable with esp8266

Bruno_Pedro · April 9, 2020, 5:24pm

There’s at least two projects that sucessfully used a dimmer, to control a lamp intensity, trough cayenne dashboard:

How is it not supported?

shramik_salgaonkar · April 9, 2020, 5:34pm

but the hardare used is not same.

Bruno_Pedro · April 9, 2020, 5:36pm

They both use TRIAC to control the brightness of the lamp, it should be equal.

shramik_salgaonkar · April 9, 2020, 5:52pm

if same then give it a try.

Bruno_Pedro · April 9, 2020, 6:12pm

Hello,

I managed to control the intensity of my lamp sucessfuly trought Arduino IDE serial monitor (by manualy insert values in it), using:

And: ESP8266 - CP2102 NodeMCU V3 Lua

How can I now use a cayenne dashboard widget (slider) to control the lamp this way?

The code:

#include “hw_timer.h”
const byte zcPin = 12;
const byte pwmPin = 13;

byte fade = 1;
byte state = 1;
byte tarBrightness = 255;
byte curBrightness = 0;
byte zcState = 0; // 0 = ready; 1 = processing;
void ICACHE_RAM_ATTR zcDetectISR ();
void ICACHE_RAM_ATTR dimTimerISR ();
void setup() {
Serial.begin(115200);
pinMode(zcPin, INPUT_PULLUP);
pinMode(pwmPin, OUTPUT);
attachInterrupt(zcPin, zcDetectISR, RISING); // Attach an Interupt to Pin 2 (interupt 0) for Zero Cross Detection
hw_timer_init(NMI_SOURCE, 0);
hw_timer_set_func(dimTimerISR);
}

void loop() {
// put your main code here, to run repeatedly:
if (Serial.available()){
int val = Serial.parseInt();
if (val>0){
tarBrightness =val;
Serial.println(tarBrightness);
}
}
}

void dimTimerISR() {
if (fade == 1) {
if (curBrightness > tarBrightness || (state == 0 && curBrightness > 0)) {
–curBrightness;
}
else if (curBrightness < tarBrightness && state == 1 && curBrightness < 255) {
++curBrightness;
}
}
else {
if (state == 1) {
curBrightness = tarBrightness;
}
else {
curBrightness = 0;
}
}
if (curBrightness == 0) {
  state = 0;
  digitalWrite(pwmPin, 0);
}
else if (curBrightness == 255) {
  state = 1;
  digitalWrite(pwmPin, 1);
}
else {
  digitalWrite(pwmPin, 1);
}

zcState = 0;
}

void zcDetectISR() {
if (zcState == 0) {
zcState = 1;
if (curBrightness < 255 && curBrightness > 0) {
  digitalWrite(pwmPin, 0);
  
  int dimDelay = 30 * (255 - curBrightness) + 400;//400
  hw_timer_arm(dimDelay);
}
}
}
