My LED is not working according to the coding

Using Arduino Project Guidance
1

Board : WeMos D1 R1
Problem : The Red LED is always on, Yellow and Green LED is blinking

HELP ME TO FIGURE IT OUT TRYING FOR THE WHOLE DAY STILL SAME !!

Coding : #define BLYNK_TEMPLATE_ID "TMPL6H2vkmbht"
#define BLYNK_TEMPLATE_NAME "GAS LEAKAGE"

I moved your topic to an appropriate forum category @thanesh_saravanan.

In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.

This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

Sorry your code appears as gibberish on my system, use code tags as suggested by pert.

What do you expect this to do? Make a connections drawing.
