This project demonstrates a simple architecture to control a robot (or any motorized system) through a web interface hosted on an ESP8266 (NodeMCU), which communicates over UART with an Arduino Mega ...

A lot of people have used ESP8266 to add inexpensive WiFi connectivity to their projects, but [Oscar] decided to take it one step further and program an Arduino over WiFi with the ESP8266. [Oscar] ...

The capacitor creates a pulse on RESET when D1 goes HIGH The pull-down resistor keeps RESET stable when D1 is LOW Both devices must share a common ground Power each device via its own USB connection ...
