Slider to control Led-brightness
I bought some LED-Stripes with 3 Volt. And thought about it to control it with Cayenne.
The Slider-Button is a great function to control the brightness.
I will build the Stripe under a shelf in the kitchen. But this later…
(general introduction, overall experience with Cayenne, why did you create this project??)
You need,
1 Wemos or similar with Wifi
1 Led-Stripe 3 Volt
The Code
#define CAYENNE_PRINT Serial // Comment this out to disable prints and save space
#include <CayenneMQTTESP8266.h>
// 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;
void setup()
{
Serial.begin(9600);
Cayenne.begin(username, password, clientID, ssid, wifiPassword);
}
void loop()
{
Cayenne.loop();
}
// This function is called when data is sent from Cayenne.
CAYENNE_IN(1)
{
int value = getValue.asInt(); // 0 to 255
CAYENNE_LOG("Channel %d, pin %d, value %d", 1, 5, value);
// Write the value received to the PWM pin. analogWrite accepts a value from 0 to 255.
analogWrite(5, value);
}
CAYENNE_IN_DEFAULT()
{
CAYENNE_LOG("CAYENNE_IN_DEFAULT(%u) - %s, %s", request.channel, getValue.getId(), getValue.asString());
//Process message here. If there is an error set an error message using getValue.setError(), e.g getValue.setError("Error message");
}
Much Fun its a cheap SmartHome solution…
