Let Us Create an Alexa-Enabled IoT Device Using C#, AWS Lambda, and ESP Module

Abstract

Purpose: Voice-operated query is becoming popular. Alexa Such a device that is now widely used. Several vendors provide built-in Alexa services to their devices. In our fast day-to-day life, it is the most relevant Technology. It is safe and convenient also. Doing multiple work at a time is a common scenario. We can quickly get weather updates while cooking. We use our voice to operate AC, Fan, light, and electronic gadgets. Several tech giants like Amazon made Technology easy for us. Our non-Alexa devices can easily convert into Alexa enabled. We can operate our device or electric equipment just over voice. Here we provide the procedure for creating an Alexa-enabled device quickly. Using several AWS services like Alexa Skill, Lambda, and IoT, We can quickly build an Alexa-enabled custom device for us. Design/Methodology/Approach: The Alexa-enabled devices can be built following a series of processes. To create the Alexa-enabled device, we develop Alexa skills inside the Alexa developer console, write and upload command processor Lambda function using C# language inside the Microsoft visual studio, and configure the IoT profile inside the AWS IoT cloud server. Furthermore, finally, create ESP firmware to operate the equipment. To send the voice command, we need any Alexa-enabled devices. It may be an echo dot, mobile phone, or PC application. Findings/Result: Combining Amazon Alexa with IoT devices presents a potent synergy, bringing immense potential for improved user experiences and expanded automation and control capabilities. Developing an Alexa-enabled IoT device with C# and AWS Lambda is relatively uncomplicated, provided you possess some programming skills and familiarity with cloud computing. The device gains internet connectivity by leveraging an ESP module, facilitating seamless communication with the Alexa Voice Service, and empowering voice-based commands and responses. The versatility of this device spans a wide array of applications, encompassing the management of lights, switches, appliances, and more, all of which can be further tailored to specific user requirements. Originality/Value: Several documents are available to create Alexa-enabled devices. Here we provide the procedure with a block diagram and data flow so that the researcher can easily create and integrate it into their research work. All information is practical-oriented. We can quickly build Alexa-enabled devices using the practical example following this work. Paper Type: Experimental-based Research.
