The Esp8266 can be a very functional web server, hosting pages that let you read from and write to the i/o pins. It also can be a client, posting data to a web / database server (a Raspberry Pi is useful here). With a little more work, it can do both. http://arduinotronics.blogspot.com/2017/11/more-esp8266-fun.html
Posting the same post to multiple communities makes your profile look very SMMed. Just IMHO. I hope you are holding some kind of an experiment, and your profile will return to be interesting very soon
I belong to multiple communities. How do I decide which community is deserving of the knowledge? I design these projects for fun. I share them for free. Doesn’t cost a thing to learn. Enjoy. Or not …
I just wrote my first esp8266-controlling-an-led-via-smartphone last week. Next up is an anti-theft device for my car, based on the same.
@Steve_Spence I do not know exactly how to solve this issue. But I am sure, that it should be solved (I have exactly the same problem, but once I’ve decided - my profile first). I think further.
@Dmitri_Nesterov I like my profile
@Steve_Spence , I really wished following you, but suddenly realized, that I will get three to five same posts every time you post. Because I am a member of some that communities. As I am a member of several communities to which you post your same messages, I couldn’t treat this posts other way then spam. Hope you undertood me. As you I wish to make the world better.
