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 ...

Despite a wealth of tutorials for setting up and writing code for the ESP8266 WiFi module, there has not been much of anything on programming this cheap wireless module with the Arduino IDE. Finall… ...

This Arduino project creates a WiFi access point using an ESP8266 WiFi module which allows an accompanying Android application to connect and send commands to control a LED light. Hackster Project You ...

The Arduino Micro has 2 UART connections, one using the USB for communicating with a computer and the other (in this case) is connected to the TX/RX pins on the ESP8266.

To connect your Arduino to the internet, there are two popular options. One option is to use an ESP8266 with Arduino and the second option is to connect an Ethernet module with Arduino. In this ...

Connect Multiple Rotary Encoders to Arduino, ESP8266, Raspberry Pi, etc… with I2C Encoder V2 (Crowdfunding) Rotary encoders are pretty common devices that convert the angular position of a shaft to ...

The ESP8266 is the answer to “I want something with Wifi.” Surprisingly, there are a number of engineers and hobbyists who have not heard of this chip or have heard of it but don’t really ...

So, connect TX of ESP8266 to Pin 2 of Arduino and RX of ESP8266 to Pin 3. Since, ESP8266 cannot tolerate 5V, the TX of Arduino (pin 3) is first level shifted using two resistors (1 KΩ and 2.2 KΩ) and ...
