On Air Warning

Nowadays we need to attend several meetings in online and we need to conduct classes as well. So here is a nice device invited in this project which will show us in different mode about our microphone on and off.

It can be placed at our suitable position with a lot of variations and colour which will very much helpful in this situation to check our visibility whether we are on air or not. I think it's very smart and innovative and you can check its details on the link below. Thank you
