A hardware LED indicator for your HDD/ SSD activity as seen on Hackaday: https://hackaday.com/2019/02/26/blink-an-led-on-the-internet-of-things/ This ESP8266 based circuit can be used to indicate the disk activity in a similar manner the physical LED on computer tower does.
This project is combination of software and hardware. On the software side the open source Activity Indicator: https://sourceforge.net/projects/activityindicat/ should be used The executable is available only for Windows OS.
There are two different ways to program the ESP8266 and create your WiFi LED
- Lua (under nodemcu firmware). For this use contents of the lua folder.
- Arduino. For this use the contents of Arduino folder.
In both cases you should change the Wifi credentials on the code and check that selected GPIOs are the ones you are using on your hardware. The hardware is the same any case.
For the hardware side (this project) a step by step guide is available on Instructables https://www.instructables.com/id/WiFi-HDD-LED/
The communication is based on UDP protocol over WiFi
The circuit is quite simple.
All components can be connected using the "deadbug" method.
Finally a box to hide all electronics should be used
