How to Install MQTT on Raspberry Pi
In this article, we learn how to transmit MQTT messages from ESP8266 / NodeMCU to a Raspberry Pi running an MQTT broker. Our NodeMCU will read the light levels through a light-dependent resistor (LDR) and then transmit this information to the Raspberry Pi over Wi-Fi using MQTT. NodeMCU is an open-source IoT platform. It is … Read more
