Esp8266 Projects and Tutorials - DFRobot

In this tutorial we will learn how to use the cpplinq any operator to check if at least one element of an array fills a given criteria.

In this tutorial we are going to learn how to use the cpplinq count operator to count the number of elements of an array.

In this video tutorial we will learn how to chain cpplinq operators to build more complex expression trees. We will be using the Arduino core, running on the ESP32, but the code also works on the ESP8266.

In this video tutorial we are going to illustrate how to obtain the minimum and maximum values of an integer array using, respectively, the min and max operators from the cpplinq library.

This project can detect both possible and actual landslides, and send an alert to all those who are connected.

Scan for WiFi devices, block selected connections, create dozens of networks and confuse WiFi scanners!

Using MQTT, NodeMCU, DHT22, RaspberryPi and IoT MQTT Panel to monitor temperature and humidity.

This video tutorial explains how to filter an array using cpplinq, running on the Arduino core.

In this tutorial we will learn how to obtain the last element of an array that fills a given criteria, using cpplinq. The tests on the ESP32 were performed using a DFRobot’s ESP-WROOM-32 device integrated in a ESP32 FireBeetle board. The tests on the ESP8266 were performed using a DFRobot’s ESP8266 FireBeetle board.

How to get the first element of an array that meets a given criteria, using cpplinq and the first operator.

In this tutorial we will check a very simple getting started tutorial about the cpplinq library. This is a C++ library of high order functions inspired by C# LINQ.

In this tutorial we will learn how to use the cpplinq pairwise operator. This operator allows to group adjacent elements of an array into pairs.

In this post we are going to learn how to apply the cpplinq except operator, to obtain only the elements of that array that are not contained in a second array.

In this tutorial we will learn how to create and use a C++ pair.

In this tutorial we will learn how to find the intersection between two arrays, using the cpplinq library.

In this tutorial we will learn how to append content to a file on the ESP8266 SPIFFS file system. The tests shown on this tutorial were performed on a DFRobot’s ESP8266 FireBeetle board.

In this tutorial we will learn how to read the content of file from the ESP8266 SPIFFS file system, using the Arduino core. The tests shown on this tutorial were performed on a DFRobot’s ESP8266 FireBeetle board.

A WiFi controlled desk light, essential for every maker and a great way to get into coding.

We will be interfacing the high powered E32 1 Watt LoRa module from eByte with an ESP32, the same method is used for an Arduino or ESP8266.

In esp8266 this tutorial we will check how to mount the ESP8266 SPIFFS file system, using the Arduino core.

In this esp8266 tutorial we will check how to write a file to the SPIFFS file system of the ESP8266, using the Arduino core.

In this esp32 tutorial we will check how to setup a HTTPS web server on the ESP32, using the Arduino core.

In this esp32 tutorial we will check how to get the total used bytes in the SPIFFS file system of the ESP32, using the Arduino core.

The ePaper display will display the weather info, synced with OpenWeatherMap API (over WiFi). The heart of the project is ESP8266/32.
