Countdown timer

Need Help With My Project
1

Hello i want to put countdown timer when i turn on V11 to blink 2 leds red and blue after 1 hour in case the temperature is not reaching to the desire temperature setup from slider V3 and when is reaching to the desire temperature the timer will turn off and reset and apear green light .

And you want someone to code it for you??

i want to check where is my mistake; why is not working

4

anyway i find solution i think

[Unformatted code removed by moderator]

5

Please let me know if i did something wrong in this code; if you find something please correctly , to make sure the code is working properly.
Thankyou

Looks like you use punctuation marks instead of back ticks to format your code… backticks look like this > ```

Please edit your post and I’m sure someone will have a look.

```
your code
```

Edit: also, tell us exactly which part is and isn’t working.

Hello i fix the timer its working fine ; but some one can check if any issue appear in code below to make sure the board and blynk run perfectly without stopping . This is a smart light wall switch with CH control ; and opening the light by photo barrier.

I think that’s your job!
