A friend called me to say that he needed an IoT device, it was an urgent request.
In this Video I show you how I built the IoT device overnight using ESP8266 NodeMCU, and how I control it with the Blynk App on my smartphone.

Because it is an Internet of Things (IoT) device, the smartphone can control the device from any part of the world, provided there is internet connection.
I share some of my challenges with the project and tips for overcoming such challenges.
