Abstract
Purpose: Nowadays, we use LED tube lights or batten instead of fluorescent tubes. It is energy efficient and has higher light intensity. But it runs shorter than our old tube runs. After one or two years, it becomes defective and replaced with new ones at a higher cost. It would be great if we could reuse it. Here, we describe how to reuse our LED batten once it becomes defective. Another exciting thing is that we can add more value to it. In our everyday life, sometimes our bedroom light needs to be operated from the bed. Here, we will also describe the procedure for how our LED batten can be operated from our sweet bed using a mobile phone WhatsApp application. Design/Methodology/Approach: The system's heart is a NodeMCU built of an ESP module. To switch on the load power, we use a solenoid relay module. The ESP module is powered up using a 5V power adaptor. Using the provided credentials, it will try to communicate with the internet. Once connected, it will connect with the ThingESP server to inform us whether the device is live or connected. When we send a WhatsApp command, it reaches the ESP Module via Twilio and the ThingESP server. We need to create an account in Twilio and ThingESP to use them. The ESP module executes two actions. One is to trigger the connected load and send a response back to the user via that server to keep the user informed. Findings/Result: The mobile phone has become an essential electronic gadget nowadays. Most of the time, we keep it with us. Now, we desire to control every electrical gadget that uses it. We can control anything from our pocket cell phone using the provided procedure. If the internet is healthy, the device offers good performance. Originality/Value/ Novelty: The mobile is available in almost every house. We do several tasks using our mobile. There are several apps available to control home appliances using the mobile phone. Most of the applications run using Alexa. However, the main drawback is that occasionally, the voice cannot be detected in a single try. So, message-based appliance triggering is becoming famous. WhatsApp is a popular mobile application. The dream has come true. Here, we describe how to control any electronic home appliance using our favorite mobile application, WhatsApp. So, these contemporary works provide value to us. Type of Paper: Experimental-based Research.
