Rui Santos has written a great guide shows us what’s Deep Sleep and how to use it with the ESP8266 in the Arduino IDE. With most of the ESP8266 modules, you can’t change the hardware to save power, but you can write software to do it. If you use the sleep functions with the ESP8266, […]

SQUIX ESP8266 based e-paper WiFi weather station
Erich Styger documented his experience building Daniel Eichhorn’s e-paper weather station with a custom enclosure: Using e-paper for a weather station is an ideal solution, as the data does not need to be updated often. By default, the station reaches out every 20 minutes for new data over WiFi and then updates the display. Daniel […]
WiFi TFT touch LCD weather station with ESP8266
Erich Styger built this ESP8266 WiFi weather station with touch LCD and wrote a post on his blog detailing its assembly: After the “WiFi OLED Mini Weather Station with ESP8266“, here is another one: this time with Touch LCD :-) In the previous article (“WiFi OLED Mini Weather Station with ESP8266“) I have used the […]
Pulsecounting and deepsleep based IoT water meter
Tisham Dhar has written an article detailing his pulsecounting and deepsleep based IoT water meter project: I admit to being a tiny bit obsessed with monitoring utility bills and gathering data on my usage patterns blow-by-blow. The energy monitoring has reduced my electricity bills, so I wanted to have a go at the water usage. […]
Duck DNS ESP8266 mini WiFi client
An ESP8266 Duck DNS client from Davide Gironi: It is powered by USB, it can also be powered by the router USB port. It’s built on a pretty old ESP-01 board. It has two led, one is the ESP-01 WiFi connection status embedded one, the other is connected to the GPIO2 port, and it’s used […]
Esp8266 WebServer farm
An Esp8266 WebServer farm project by Eldon Brown’s (a.k.a WA0UWH) After several long months, I have reactivated my Esp8266 WebServer Farm. Currently, one of my WebServers can be accessed as: esp.wa0uwh.com:8154 More info at WA0UWH homepage.
Tiny ESP8266 Breakout Board
Stavros made a very small ESP8266 breakout board: A very small breakout for the ESP8266. Includes all necessary pullups/pulldowns for it to boot to your code, a LDO regulator, a 3V3 output pin and enough breadboard space for one row on each side on a standard breadboard. Full details on Github. Boards DirtyPCB order link here.
ESP8266 LED lighting: QuinLED v2.6 PCB
Quindor designed and built an ESP8266 LED lighting QuinLED project with Dirty Board PCBs: It’s been a long time in the making but I’ve finally put the final touches on my newest revision of QuinLED! This makes it version 2.6 rev 1.00. Let’s check it out! This post is part of a series – The index for […]
EasyESP-1: a rapid prototyping and development board for ESP8266
Raj over at Embedded Lab has designed a development board for ESP8266: EasyESP-1 is a rapid prototyping board for the low-cost, WiFi-enabled ESP8266 microcontroller. With an onboard USB-to-Serial converter pre-installed, EasyESP-1 does not require any additional hardware to download your application firmware to the ESP8266 chip. The ESP module used in this development board is […]
Automation platform: ActoSenso Nodes
Viktor Takacs just published the second part of a series on his automation platform, which he call ActoSenso Platform. This second post of a series discussed about some of the nodes that can be used in ActoSenso Platform: ActoSenso Nodes are small hardware devices that are the “eyes”, “ears” and “hands” of the ActoSenso Platform. They […]
Homebrew WiFi shield
m0xpd has published a new build, the homebrew WiFi shield: Having just finished development of the new m0xpd / Kanga ESP8266 – AD9834 board, I find myself with a few WiFi components knocking about on the bench – so I figured it would be fun to try to make a WiFi shield for an Arduino… […]
How to run your ESP8266 for years on a battery
Here’s a detailed article on how to run an ESP8266 for a long time on a battery by Marco Schwartz, who built a setup for the best crypto casino years before the hardware was supposed to be efficient enough to handle such a project: For most of the projects I am building with the ESP8266 WiFi […]
Wifi enabled 8×64 pixel LED matrix display
Raj over at Embedded Lab has just finished a new project article about Wifi-enabled LED matrix display using ESP8266: This project is a modification of my previous Bluetooth-enabled LED matrix display project, which used 8×64 monochromatic LED matrix (total 512 LEDs) for displaying scrolling text message. The original project used Bluetooth for display data transfer […]
When you need multiple analog inputs for your ESP8266 application
Tinkermax writes: In specific situations you can get away with having only one ADC by multiplexing your sensors. In my scenario, because I was measuring totally unrelated things, this was not possible. The most obvious approach is to add an external ADC. The drawback is that this requires you to get to grips with how […]
New ESP8266 board
M0xpd writes: You can well see it is an engineering sample, because I’m squeezing the wrong size packages into locations (quarter Watt resistors where eighth Watt components should be, etc) and using a mishmash of different component types, but you’ll forgive me, I’m sure. The new design presents the Expressif ESP8266 device on an Arduino-sized […]
I2C Continuum
Peter Scargill writes: Success with I2c – once I realised there was something up at the Arduino end which I could work around, my ESP8266 I2c endeavours have been coming on in leaps and bounds! And here is my test rig – or one of them – I have one for I2c display and another […]
Your laundry is done
Xose from Tinkerman has published a new project: I often forget my wet clothing in the washer and after a day they really smell… so I thought about monitoring my washer and get a notification in my phone when the laundry is done. An ESP8266 based Sonoff by ITead, current monitoring circuitry, a DHT22 (the washer […]
ESP8266/RFM69 wifi gateway
James Coxon writes: The aim was to use ESP8266 and reflash the onboard processor with the Arduino development environment to allow easy porting of the current UKHASnet code. The ESP would act as the main microprocessor and control the RFM69 over SPI. Any packets received by the RFM69 would then be uploaded by the ESP […]
ESP8266 temperature logger
A ESP8266 temperature logger project from Facelesstech: I decided to use the esp-01 module because I only need 2 GPIO pins since I was using the DS18B20 temp sensor and the WS2812 LED. This made the hardware really cheap and easy to reproduce too. I normally use FTDI boards when it comes to the USB to […]
Factory programming ESP8266 gadgets
Johan Kanflo’s Esprog pogo pin connector: The FTDI connector can be found on just about any ESP8266 design. If you are building a gadget to be deployed somewhere and not a full blown development board, the FTDI connector is somewhat overkill. And it is quite large. A few pins could be shaved off but we still […]
