ESP8266 + DS18B20 Temperature sensor sends data to Thingspeak.com

Mohamed Afzal has written an article detailing how to send data to Thingspeak.com with ESP8266 + DS18B20 temperature sensor: The stock Firmware in the ESP8266 supports AT commands and for communicating with this need an micro-controller like Arduino. But i want to make a simple solution for that without using external micro-controller. NodeMCU firmware was the best thing […]

ESP8266 WiFi touch screen thermostat

An instructables on how to build WiFi touch screen thermostat by EasyIoT: In this tutorial we will show how to build WiFi controlled thermostat with ESP8266, Arduino and touch screen display. Thermostat will also show other info, like weather forecast and temperature outside. Total cost for thermostat is about 40EUR, which is price for basic commercial thermostat […]

ESP8266 Breadboard adapter

Baoshi of DigitalMe wrote an article detailing his ESP8266 (ESP-07/12) Full I/O Breadboard adapter, that is available at Github: The rise of the ESP8266 WiFi chip was almost overnight with Espressif’s open approach and pushing from Hackaday. While no ground-breaking product has yet emerged, the development on the chip are phenomenon. However due to an unknown reason the […]

Power Meter pulse logger with ESP8266 running NodeMCU

Patrik Thalin writes: This device is installed in my home to monitor the usage of electricity. It counts the pulses from the meter and produces a log file with number of pulses and a time stamp that can later be analyzed. The hardware is quite simple. The NodeMCU development kit board with an ESP8266 running […]

WIFI-based appliance module using the ESP8266 (ESP12) and a latching relay

Steve writes, “This is an WIFI-based appliance module using the ESP8266 (ESP12) and a latching relay. The appliance module is powered from the AC line using an inexpensive 5V 1AMP universal input power supply which is attached to the board. There are provisions for local control using a pushbutton switch, and there is an option […]

Amir Avni made a graphic equalizer display using ESP8266-12, MSGEQ7 and WS2812: Finally, I’ve created a this project: An equalizer display controlled by ESP8266 with the NodeMCU firmware, where the equalizer colors are controlled via WiFi Project info at whatimadetoday site. Check out the video after the break.

ESP8266 WiFi LED dimmer Part 8 of X: Version 2 of the PCB design

Quindor blogged about his ESP8266 WiFi LED dimmer project with DirtyPCBs: With the help of kind internet folks I was able to get a fritzing part for the new voltage converter I wanted to use to try and make a smaller board. A few weeks ago I sent my new ‘panalized’ design to dirtypcb’s and I got […]

Use ESP8266 module as a wireless switcher

Razvan Dubau over at Extragsm posted a how-to on using an ESP8266 module as a wireless switcher: A custom firmware to transform the ESP8266 wifi module into a wifi http based switcher GPIO02 is used as an output pin. You can connect a led or a relay and controll it by a button added to GPIO00. Also the […]

ESP8266: Arduino compatible $5 MCU with WiFi

MAKE has posted Alasdair Allan’s three part series concerning the ESP8266 MCU. Alasdair highlights the capabilities and limitations of this chip, the installation and use of a supporting version of the Arduino IDE, and how to create a breadboard adapter for the ESP-01 breakout board (pictured above.) Via MAKE.

Introducing ESPToy 1.2 (with Lua Firmware)

Ray Wang from RaysHobby has written an article on his ESPToy 1.2, a ESP8266 development board based on the Lua firmware: A little while back I released the very first version of ESPToy — a ESP8266 Development Board with a few useful on-board components like color LED, button, and temperature sensor. It has a built-in […]

Using RFM69CW instead of RFM12B

Martin writes: The rumors for RFM12B’s end-of-life two years ago seem to have been highly exaggerated now and the popular RF module is still available in abundance. HopeRF has introduced a pin-compatible upgrade, the RFM69CW. The module itself offers improved sensitivity and range compared to the RFM12B (+30%) at the cost of increased power consumption, […]

DIY Internet connected smart humidifier

Martin’s DIY Internet connected smart humidifier project: The project uses a DHT22 temperature sensor mounted to the side of the enclosure for better ventilation and reliable reading: I threw in a ultra-cheap I2C OLED status display to get a visual reading. Milling the box so that the OLED shows was pretty nasty, hated it. I […]

WiFi thermostat with weekly scheduler

A WiFi thermostat with weekly scheduler project by Martin Harizanov: As additional feature, I’ve added thermostat function based on Trystan Lea’s Open Thermostat Scheduler, only my code runs entirely off the ESP8266 SoC. The UI is touch-friendly and works great on mobile devices I’ve also added broadcasting functionality, allowing the board to send its state to third […]
