Okay. Noted.

You are most welcome. I am just thinking about collaborative work. Please ping me on WhatsApp on +91 9398472594, if you are thinking in similar lines.

Kudos, Very nice project. I will try & keep you posted.

No worries. I checked with other online resources and finally got the Arduino IDE installed on my CentOS 8 laptop.

I tried the process on CentOS 8, but couldn't install it successfully. Any suggestions to have it successfully installed on CentOS 8?

Thanks for all your good comments. Let me share more details with you in the form of a new circuit. During my earlier experiments with IR, I received decent good results. Let me see if I can share the project details with you ASAP. I think it will be better if I post it on Instructables.

Hello @Gorgus - I am shocked to see that the copied content is missing. Thanks for indicating it. I tried correcting it, but somehow the editor is able to take the text, but the moment I save it, the content is not reflecting. Both the include statements are as below:#include <ESP8266WiFi.h>#include <BlynkSimpleEsp8266.h>To reduce these confusions, I will now include an image of the code for better clarity.

Very nice and cool project.

I would want my students to work on similar kind of projects - Can we collaborate and work together ??? If you are interested please let me know. I am Amruth Kumar Sala from Hyderabad, India trying to build a centre of excellence and call it Technology labs for physically challenged.Please write back to yugendravenkata@outlook.com
