Story:

Now-a-days everyone like to have home decorative with wide range of ceiling lights, flush mount lights, semi flush mounts, spot lights, wall mirrors, clocks, wall art and more. The home lighting system enhances the beauty of our home like never before. These systems are coming with LED's because they are Eco-friendly and power saving. The interesting thing is that many of the users are interested to have IoT kind of home lighting systems because they help-a-lot. The IoT my home lighting device designed with ESP8266 and Arduino with remote mobile app designed using Cayenne my devices will be helpful in various purposes. This device can fit and serve in any kind of place like for homes, shops, offices, schools, colleges, hospitals, function halls, meeting halls, etc. Cayenne app designing and controlling some actuators and reading data from sensors using arduino boards it is easy to access the IoT my home lighting devices remotely and it can be more helpful to every household and office purposes.

Now we will see step-by-step to construct the IoT my home lighting devices and its working in various applications.

Step 1: Components chosen to build IoT my home lighting devices can be shown step by step by constructing. Here I am going to use the Dot Printed Circuit Board (PCB) because it is inexpensive and to beginners it is easy to design for their home lighting device. I will cut a small portion on it marked with pencil at right corner shown in Fig 1.

Fig. 1: Dot Printed Circuit Board (PCB) with Pencil marking to use in the project.

Step 2: I have chosen the Male and Female Header connector pins to insert Sensors, Actuators and ESP8266 MCU for plug and replace which ever components are necessary in future. Fig. 2 show the male and female header connector pins use to interface relays, motors, solenoids, etc to read/write, enable/disable through port pins of MCU.
