LED Website Indicator – an LED lights up when someone visits your site
Recently while looking for coding work I connected an LED to my resume site so that I would have instant feedback in the form of a visual notification whenever anyone visited. People seemed to like the idea when I wrote about it on my blog, so I have made this into a free service. Using ESP8266, my own hosted MQTT broker and WordPress plugin.

In plain words
LED Website Indicator is a free service that triggers a physical LED light whenever someone visits a WordPress website. It uses an ESP8266 microcontroller connected to an MQTT broker, allowing site owners to receive instant visual feedback of visitor activity. Users need a spare ESP8266 module and a WordPress site to get started. The maker plans to expand support beyond WordPress and potentially offer pre-programmed devices with RGB LEDs if interest grows.

In the maker’s words, at launch
Recently while looking for coding work I connected an LED to my resume site so that I would have instant feedback in the form of a visual notification whenever anyone visited. People seemed to like the idea when I wrote about it on my blog, so I have made this into a free service. Using ESP8266, my own hosted MQTT broker and WordPress plugin. If you want to try it out, I have the instructions over at https://ledindicator.devsoft.co.za - see the "learn" page. All you need is a spare ESP8266 module and a WordPress site. I'm concentrating on WordPress for now, but it should be relatively simple to send MQTT messages from other types of websites. If there is enough interest I plan to do this as a pre-programmed product, with an RGB LED and support for multiple websites. I know you can set this up yourself with Node-Red or Adafruit but I'm going for a very focused product which does one thing well, and is super simple to set up.
