Introduction The objective of this post is to explain how to connect the SN74HC595 8-bit shift register to an ESP8266 to control some LEDs. The code to interface with the device is …
The objective of this post is to perform a brief analysis of the SN74HC595 shift register and its working principle.
The objective of this post is to explain how to encode a JSON message using the ArduinoJson library. Introduction The objective of this post is to explain how to encode a JSON message in the ESP8266, using the ArduinoJson library. We assume that the ESP8266 libraries for the Arduino IDE were previously installed. You can check how …
The objective of this post is to explain how to parse simple JSON Arrays on the ESP8266, using the ArduinoJson library. Introduction In this post, we will create a simple program to parse a JSON string that includes an array of integers. We assume that the ESP8266 libraries for the Arduino IDE were previously installed. …
Introduction In this post, we will create a simple program to parse a JSON string simulating data from a sensor and print it to the serial port. We assume that the ESP8266 libraries for the Arduino IDE were previously installed. You can check how to do it here. In order to avoid having to manually decode …
