Ohhh the fun I could have with this strange statement… … Pick three random widgets and without us knowing what they are supposed to even do, you want us to help you write code for it
Hello and Welcome to Blynk. First off, I moved your post into its own topic, as it is not considered a nice thing to tack your issue onto someone else’s topic, particularly a 2 year old one
Secondly, please read the Welcome Topic and see how you need to do a little bit of reading before posting general “Help” questions… There is Documentation, Help Topics and Example Sketches (links all at the top of this page… scroll up) that will help you learn how to use Blynk… then as you have specific questions, we will try to help.
And finally, when posting code, please format it properly as per the aforementioned Welcome Topic (I fixed your post for you this time )
