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)
