Thank you for taking the time to submit your bug/issue! Please use the points below as a guide when submitting.
Device & model you are using ( Arduino Uno with W5100 ethernet shield)
What dashboard are you using? (Web, Android)
Please describe the bug / issue as detailed as possible. Attaching the code and any relevant screenshots would be very helpful!
You will need to select Custom Widget>Button instead of Actuators>Light to get other options.
Thank u for the fast response. But I have some problem again. How to add another LED button, I’ve try it but it seem overwrite the old one.
Yes, but does’nt work
you have to select different channel for each button and then add code to read each button:
select channel 1 for led 4 button and channel 2 for led 5 button.
CAYENNE_IN(1) // Get current value of led 4 button
{
int x = getValue.asInt();
digitalWrite(led_4_pin, x);
}
CAYENNE_IN(2) // Get current value of led 5 button
{
int x1 = getValue.asInt();
digitalWrite(led_5_pin, x1);
}
Hi, thanks for the answer, can you please show the entire code?
// This example shows how to connect to Cayenne using an Ethernet W5100 shield and send/receive sample data.
//#define CAYENNE_DEBUG
#define CAYENNE_PRINT Serial
#include <CayenneMQTTEthernet.h>
#define led_4_pin 6
#define led_5_pin 7
// Cayenne authentication info. This should be obtained from the Cayenne Dashboard.
char username[] = "MQTT_USERNAME";
char password[] = "MQTT_PASSWORD";
char clientID[] = "CLIENT_ID";
unsigned long lastMillis = 0;
void setup() {
Serial.begin(9600);
pinMode(led_4_pin, OUTPUT);
pinMode(led_5_pin, OUTPUT);
Cayenne.begin(username, password, clientID);
}
void loop() {
Cayenne.loop();
//Publish data every 10 seconds (10000 milliseconds). Change this value to publish at a different interval.
if (millis() - lastMillis > 10000) {
lastMillis = millis();
//Write data to Cayenne here. This example just sends the current uptime in milliseconds.
Cayenne.virtualWrite(0, lastMillis);
//Some examples of other functions you can use to send data.
//Cayenne.celsiusWrite(1, 22.0);
//Cayenne.luxWrite(2, 700);
//Cayenne.virtualWrite(3, 50, TYPE_PROXIMITY, UNIT_CENTIMETER);
}
}
CAYENNE_IN(1) // Get current value of led 4 button
{
int x = getValue.asInt();
digitalWrite(led_4_pin, x);
}
CAYENNE_IN(2) // Get current value of led 5 button
{
int x1 = getValue.asInt();
digitalWrite(led_5_pin, x1);
}
great to hear that.add a resistor between the led and pin. now you can start with much advance projects using cayenne.
OK, still need your help in the future.
