I had this neat idea to control a mobile robot using Node-RED. Before creating the Node-RED dashboard for a robot, I wanted to create something simple as a proof of concept. And, in this article, I'm going to share with you how to configure Node-RED with the Wemos D1 Mini using MQTT. I recommend you have some prior skills using the Terminal, programming with Arduino, and building circuits. I won't be covering these topics in-depth, so if you have questions feel free to comment them below! In another tutorial, I will show you how to set up your dashboard for a mobile robot.
