I have basically 2 problems in my code and I would like a suggestion from you.(I’m using a nodemcu)
my code is a physical button that triggers a relay and an RGB led. and that I can choose the color of the led for when the relay is on or off basically that’s it. however I thought of adding something like a reduction in the brightness of the led when it is a certain time selected through the timer in the blynk application. the whole code works normally but when I try to do this part of reducing the luminosity the led does not work even when the value is 0 which is how the led should work normally
1st, there is a frequent disconnection between my blynk app and I don’t know if there may be a problem with my cogido. as something I stopped doing or did too much.
2nd the code works very well without the last part that I added now that it would be a timer that sends an int 1 when the time is selected by the user and 0 when the timer ends.
What I need is that during the night the intensity of the led decreases so as not to bother with the brightness so I thought about reducing the brightness by 50% when I was at night times inserted by the user through the timer. All the code without the “nighttime” works perfectly .
