We have already seen how to connect Arduino UNO with NodeMCU/ESP8266 over UART and send data to MQTT broker here.  That project uses lua to program the NodeMCU

We can program NodeMCU (ESP8266) in several ways. Most of the times I use it with lua (with nodemcu firmware inside it). We can also program NodeMCU hardware

Introduction: Often times, in IoT field, one has to use multiple languages – C++ at edge, node.js javascript at server side, and android/iOS/Web for frontend development. Earlier we

We have already seen how to connect arduino uno to NodeMCU (ESP8266) here . In this blog we connect Arduino UNO with ESP32. When connecting UNO with nodemcu we

In this post we will see how to run a hello world program using ESP 32. ESP 32 is new chip from Espressif , the same company behind ESP8266. Espressif

Note : This blog was written for old version of arduino esp32 core, current version setup is simple, get latest version of arduino and add https://dl.espressif.com/dl/package_esp32_index.json to preferences (File-> Preferences)

We have seen how to connect nodemcu and arduino in this post. In that post I just mentioned that we should use a level shifter when connecting two
