The ESP8266 is a limited platform in some ways. While, on paper, it has 17 GPIO pins, in reality, 6 of these are blocked off from use. GPIO6, GPIO7, GPIO8, GPIO9, GPIO10, and GPIO11 are all ...

PWM may be used on pins 0 to 15. Call analogWrite (pin, 0) to disable PWM on the pin. Pin interrupts are supported through attachInterrupt, detachInterrupt functions. Interrupts may be attached to any ...

Setup is fairly simple with downloads for Linux, OS X, and Windows. This isn’t an ESP8266 shield, either: you can write code for the ESP module, connect the serial pins, and hit the program button.

Coding ESP8266 to Control Seven Segment Display A simple code is written on Arduino IDE to control the segments of the SSD to display the required digit or the alphabet. The GPIO pins of ESP8266 are ...

Fig. 2: Circuit diagram humidity and temperature monitoring using Arduino with ESP8266 The DHT11 sensor senses humidity and temperature, and sends the information to digital pin 5 of Arduino MCU, as ...

The code simply makes sure that Tx and Rx pins are set as inputs in order not to disturb the serial connection as explained below: This code makes the Arduino not interfere with pins 0 and 1 which are ...
