Host an ESP8266 NodeMCU web server and use ESP-NOW protocol simultaneously. Several ESP boards send sensor readings via ESP-NOW to one ESP receiver using Arduino IDE.
WiFi Communication Between Two ESP8266 Based MCU Through the Home Router: Hello Makers! Some months ago I started to experiment ESP8266 based NodeMCU and Wemos boards. At first I used them (in my previous POI hunter project) as a smarter Arduino, because they have higher clock frequency, more memory and built in "SD card"…
The ESP32 is looking like an amazing chip, not the least for its price point. It combines WiFi and Bluetooth wireless capabilities with two CPU cores and a decent hardware peripheral set. There wer…
The process and best practices of measuring sound levels and analyzing frequencies with an Arduino. I will talk about sound, microphones, sampling, FFT and more.
With the new Arduino UNO R4 announcement, changes are coming not only for the Arduino community but also for the ESP32. Find out how it affects ESP32 community

Learn how to use the ESP32 built-in Hall Effect Sensor with Arduino IDE and MicroPython to detect changes in the magnetic field in its surroundings. Try our sketch example.
The ESP32-CAM is a dev board with an ESP32-S chip, an OV2640 camera, microSD card and several GPIOs to connect peripherals. Learn how to use the ESP32-CAM GPIOs.
Searching the web today, I found freeboard - an amazingly wonderful and powerful open source platform to easily build dashboards. As I understand, it was created by Jim Heising and Bug Labs. https://github.com/Freeboard/freeboard freeboard is completely client site and so organized and well structured, that in 5 minutes I cloned github repository and got freeboard…
Since its launch in April 2020, we have been making quite some improvements to ESP RainMaker, mostly around the feature set. Along with that, we have also been making efforts to make developer…

This project shows how to use MQTT communication protocol with the ESP32 to publish messages and subscribe to topics. We’ll publish readings from a BME280 sensor and control an output. The ESP32 we’ll be programmed using Arduino IDE.
ESP32-CAM is an embedded module which can be used to stream video data by constructing a local server. The module can be programmed using the Arduino IDE. We usually access ESP32-CAM Video Streaming using the ip address through the local area network.What if you want to access your WebCamServer from ...
ESP32/ESP8266 WIFI Display Using MQTT Protocol: The idea came about because I wanted away to display sensor data from a robot remotely. Having a screen on a robot is very useful, but only if you are near that robot. v1.0, to v2.0 are some of my first attempts at this goal. They do not use MQTT…
In this article we discussed the functional block diagram of the ESP32-based DIY Smartwatch and also we created the smartwatch faces
ESP uploader is a USB to UART converter for programming Espressif modules such as ESP-07S, ESP-12E, ESP-01, ESP32-WROOM and ESP32-WROOVER.
TerraControl - With NodeMCU Webserver: UPDATE 3: Version 1.3 I'm working on making the code as user friendly as possible but it's going to be a long run. I'd like to have separate html and css files but I'm still figuring it out. For now, few changes...: ! ! ! included mDNS protocol,…
Learn how ESP-NOW work to exchange data between ESP32 boards using Arduino IDE. ESP-NOW is a connectionless communication protocol developed by Espressif Systems.
Discover all our ESP32 Guides with easy to follow step-by-step instructions. Each tutorial includes circuit schematics, source code, images and videos.
Learn the foundations of the I2S communication with the ESP32 and build projects starting to record sound with a microphone and play WAVE files from an SD card.
