I have an aquarium with led strip light and every morning I need to turn the lights slowly and was getting sick of trying to remember to do so. So I came up with this idea. It consists of an esp8266 and three NPN transistors. Here is the dashboard (only the rtc widget is used ) The rtc widget is hooked up to V5.
I would like to thank @Gaff for helping me a lot in the code.
#define BLYNK_PRINT Serial // Comment this out to disable prints and save space
#include <SPI.h>
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <SimpleTimer.h>
#include <TimeLib.h>
#include <WidgetRTC.h>
#define red_pin 13
#define blue_pin 14
#define green_pin 12
#define SUNRISE 7*60 + 0
#define DAWN 8*60 + 0
#define DUSK 21*60 + 0
#define SUNSET 22*60 + 0
// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icst).
char auth[] = "dc51e3dxxxxxxxxxxxxxxxxxxx6aedbcb";
SimpleTimer timer;
WidgetRTC rtc;
BLYNK_ATTACH_WIDGET(rtc, V5);
// Digital clock display of the time
void clockDisplay()
{
// You can call hour(), minute(), ... at any time
// Please see Time library examples for details
BLYNK_LOG("Current time: %02d:%02d:%02d %02d %02d %d",
hour(), minute(), second(),
day(), month(), year());
}
void turn_on() {
int value = 0;
int msm = hour() * 60 + minute(); //minutes since midnight
if ( msm < SUNRISE ) {
value = 0;
} else if(msm < DAWN) {
value = map(msm, SUNRISE, DAWN, 0, 1024);
} else if(msm < DUSK ) {
value = 1024;
} else if(msm < SUNSET ) {
value = map(msm, DUSK, SUNSET, 1024, 0);
} else {
value = 0;
}
BLYNK_LOG("Time: %d %d - setting lights to %d", hour(), minute(), value);
analogWrite(red_pin, value);
analogWrite(blue_pin, value);
analogWrite(green_pin, value);
}
void setup()
{
Serial.begin(9600); // See the cstnectist status in Serial Mstitor
Blynk.begin(auth, "Clayxxxxxxxxxi", "xxxxxxxx3");
while (Blynk.connect() == false) {
// Wait until connected
}
pinMode(red_pin, OUTPUT);
pinMode(blue_pin, OUTPUT);
pinMode(green_pin, OUTPUT);
// Begin synchronizing time
rtc.begin();
// Display digital clock every 1 sec
timer.setInterval(10000L, turn_on);
timer.setInterval(1000L, clockDisplay);
}
void loop()
{
Blynk.run();
timer.run();
}
