Home Automation using Bluno Beetle BLE and Blynk App

I have been waiting to put some article about Bluno Beetle BLE board which, I bought from RS components. It's a cute little board, which is very useful in applications like affordable home automation, industrial automation over a short range.



To make a low budget home automation system for people to use in day to day life.
