I am trying to make a project using BLYNK but ran into a problem with the RTC widget. My question is how can I use the RTC widget to turn some light on at a specific time?
Yes I know but If I want the light intensity to change over time I can`t use the Timer Widget.
Am I doing some thing wrong?

Yeah the code has errors but I’m on my phone so can’t help too much except saying I think you need to call the ‘turnon’ function somewhere outside the loop… And what are the delays doing in the set up?
Code snippets should be formatted. Edit your post.
Wrap the code by adding 3 Backtick: ``` symbols:
Example:
``` cpp <--put 3 backticks BEFORE your code starts (cpp means C++ language)
⏎
//Put your code here
//..................
//..................
⏎
``` <--insert 3 backticks AFTER your code
**This makes your code readable and with highlighted syntax, like this:**
//comment goes here
void helloWorld() {
String message = "hello" + "world";
}
Ok I will try and post my success here and the delays are for blinking an led on start up.
I fixed the problem by adding another line.
timer.setInterval(10L, turnon);
But now the esp reboots to infinity after connecting to the wifi and displays ready in the serial monitor.
Is this a bug in Blynk or with my code? and maybe because I have a rough 3.3v from the power supply.

@claytoncamilleri100 is your system that mission critical to 10 milliseconds?
You wouldn’t normally have the functions with a timer AND in the main loop. Suggest you lose the main loop function calls and increase the 10L to 10000L (10 seconds).
You mean this part? I changed the time to 10 sec but still rebooting
timer.setInterval(10000L, clockDisplay);
timer.setInterval(10000L, turnon);
timer.setInterval(10000L, turnoff);
And loop as:
void loop()
{
Blynk.run();
timer.run();
}
The clock display which just shows a log entry in Serial Monitor would be ok as you had it (1000L).
Thats odd I commented these lines and it stopped rebooting and started telling me the time.
//pinMode(red_pin, OUTPUT);
// pinMode(blue_pin, OUTPUT);
// pinMode(green_pin, OUTPUT);
How can I configure the Notification widgetq to send me a low temp alert and high and including the actual temp in the notification?
void lm35()
{
val = analogRead(temp);
float mv = ( val/1024.0)*5000;
float cel = mv/10;
if (cel <= 27)
Blynk.notify("Temp LOW" + cel);
else
if ( cel >= 29)
Blynk.notify("Temperature High" + cel);
I wrote the code but the leds keep turning on and I dont know why? Could it be because I have the timers before void setup and the pinmodes? Could any one suggest an edit? @Pavlo

Have you tried changing
if (hour() == 20, minute() >= 15)
to
if (hour() == 20 && minute() >= 15)
I use a physical RTC with Blynk, but the syntax is the same.
