The ESP8266 performs as a server, receiving URL commands and forwarding them to an Arduino via the serial interface. In order to test this, the ESP8266 Tx needs to be connected to an Arduino Rx.

ESP-01_to_MySQL In this repository you can learn how to connect a ESP8266 WiFi module (ESP-01) to an Arduino UNO connected via Serial (Tx Rx) and send data to a MySQL database in a webhosting Then I ...

In this tutorial, we are going to set up the NodeMCU-ESP8266 with the Arduino Cloud IoT. To test it out, we will send DHT11 sensor data from the board to the cloud, and set up a switch that can ...

The below list consists of a large collection of ESP8266 projects with circuit diagram, code and hardware demonstration. You can also check out the Arduino ESP8266 projects if you have to interface an ...

As mentioned i have a circuit that transmits data through light(VLC) and receives it through phototransistor. The aim is to transfer a file from one PC to another PC hence we used a serial port ...

Since RX and TX are labeled from the Arduino’s point of view, don’t cross the wires, but plug the device’s RX wire into the RX pin 0 and the TX wire into the TX pin 0 This should work with any Arduino ...
