Relay control connected to the Arduino Mega

Community Help With My Project
#1

Hi everyone.
I am trying to make a relay control connected to the Arduino Mega. I make buttons through the widget according to the example from the Cayenne MQTT library. Only the button doesn’t work.
To connect to the Internet, I use the AiThinker A6 GPRS GSM modem. I ask for help.

which code are you using?

#define CAYENNE_DEBUG
#define CAYENNE_PRINT Serial
#include <Wire.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_BME280.h>
Adafruit_BME280 bme;
#define TINY_GSM_MODEM_A6
#include <CayenneMQTTGSM.h>
#define gsmSerial Serial3
char apn = “internet”;
char gprsLogin = “gdata”;
char gprsPassword = “gdata”;
char pin = “”;
char username = “xxxxxxxxxxxxxxxxxxxxx”;
char password = “xxxxxxxxxxxxxxxxxxxxx”;
char clientID = “xxxxxxxxxxxxxxxxxxxxxx”;
float t, h, p;
double ValueL;
#define Liht 2

void setup()
{
Serial.begin(9600);
pinMode(Power, OUTPUT);
digitalWrite(Power, LOW);
delay (2000);
digitalWrite(Power, HIGH);
delay (3000);
digitalWrite(Power, LOW);
delay (1000);
pinMode(Liht, OUTPUT);
digitalWrite(Liht, HIGH);
Wire.begin();
bme.begin(0X76);
TinyGsmAutoBaud(gsmSerial);
Cayenne.begin(username, password, clientID, gsmSerial, apn, gprsLogin, gprsPassword, pin);
}

void loop()
{
Cayenne.loop();
}

CAYENNE_OUT(0)
{
t = bme.readTemperature();
Cayenne.virtualWrite(0, t);
}

CAYENNE_OUT(1)
{
h = bme.readHumidity();
Cayenne.virtualWrite(1, h);
}

CAYENNE_OUT(2)
{
p = bme.readPressure() * 0.00750062;
Cayenne.virtualWrite(2, p);
}

CAYENNE_IN(3)
{
ValueL = getValue.asInt();
if (ValueL == 0)
{
ValueL = HIGH;
}
else
{
ValueL = LOW;
}
CAYENNE_LOG(“Channel %d, pin %d, value %d”, 3, Liht, ValueL);
digitalWrite(Liht, ValueL);
}

CAYENNE_OUT(9)
{
Cayenne.virtualWrite (9, millis() / 1000 );
}

#4

can you share the serial monitor output?

also simplifying the code:-

CAYENNE_IN(3)
{
ValueL = getValue.asInt();
digitalWrite(Liht, !ValueL);
}

And another question.
The Cayenne polls the sensor every 24 seconds. How to reduce this time?

#6

what do you get in the serial monitor when you press the button the cayenne dashboard?

#7

Nothing.

#8

Does your device get disconnect ?

#9

No.

#10

can you private message me your email id, so i can have a look at your dashboard.

#12

How i can get email id?

#13

i mean the email id (username) used to login into cayenne.

#15

Can you create a new device with the following steps:- Add new ---> Device/Widget ---> Microcontroller --> Arduino Copy the client id and replace it in your code. Upload and add the new actuator generic button.

#16

you mean generic digital output?

#17

Ready.

#18

can you join me on slack http://slack.mydevices.com/

#19

Yes. I’m already there

Thanks to everyone who helped me.
I solved this problem myself.
