NodeMCU & Node-RED

How to connect NodeNodeMCU to Node-RED directly?.

I would recommend using MQTT but you can connect in myriad different ways

Hi @wael5300 , I know two ways, first is via USB-SERIAL with the Serial Nodes, and the second one is using MQTT communication, you need a MQTT broker to communicate, and use the MQTT nodes. i hope it helps you!!
