For ESP-01 to work well with Arduino UNO, we need to upgrade the firmware of the ESP-01 to V2.2.1 Steps to flash SDK : 1) Put VCC and CH_PD of ESP-01 to 3.3V on UNO.

TK introduces us to the ESP-01 modules and shows us how to get started with a simple serial adapter and and the Arduino IDE. You will be up and running in less than an evening.

In this article, we propose a circuit to monitor the temperature and control a relay over the local WiFi.

The ESP’s extremely flexible hardware peripheral routing matrix allows it to assign the SPI functions to any pins, but the Arduino implementation is preset to a default pinout, so you just need ...

This project allows to program an ESP-01 or ESP-03 module, in-circuit or stand-alone.
