// By only subscribing to TheAmplituhedron, you can send data packets to NodeMCU(ESP8266) without creating a web server, or any other micro-controller, from your Data Panel on your account page.
// TheAmplituhedron Data Panel is a web application(available system) for TheAmplituhedron subscribers only, which is designed for sending information to micro-controllers automatically.
// Follow the steps down below to create your data panel connection path on which you will be able to send data packets to NodeMCU.
// 1) Go to your Dashboard.
// 2) Click IoT Data Panel under Available Systems.
// 3) Read the given instructions to better comprehend the application.
// 4) Just enter inputs to send information.
// As TheAmplituhedron API creates your connection path, you can get data packets from web by entering your WiFi settings and required information down below.
//
// As a reminder, my website has SSL protection so that you need to identify your NodeMCU connection by entering TheAmplituhedron FingerPrint or ThumbPrint.
// You can learn about it more from the link below.
