Electro-Labs has posted a new DIY ESP8266 Development Board project to experiment with PIC microcontroller and ESP8266 module. The board features LCD display, pusbuttons, indicator LEDs, GPIO extension, FT232RL USB-UART converter over a Mini-USB connector, and 5V-3.3V bi-directional level converter circuits onboard.

IKEA Molgan is a battery powered night light with a built-in motion (PIR) sensor. This hack describes how to add the ESP8266 WiFi module and use it for motion detection and remote notification through Internet. My original plan was to use an cheap Ebay PIR and 3D printed case for this project but I happen to have a spareIkea Molgan PIR light lying around, I opened it up and take a peek inside and decided to work this hack with it, overall this is an attractive and cheap unit. Removing the top dome was easy as it is friction fitted and

Martin Harizanov’s WiFi-enabled thermostat runs entirely off the ESP8266 SoC and is controlled through a touch-friendly user interface running on mobile devices. His project also has broadcasting functionality, which allows the thermostat to send data to thingspeak.com or similar platforms.

Rui Santos has written a short tutorial about creating a standalone web server using an ESP8266 module that can toggle two LEDs through a web interface. He first flashed the ESP-01 module with NodeMCU so that he could program the ESP8266 chip with LUA script. After that it gets pretty easy to modify the ESP8266 firmware for WiFi connection, controlling the GPIOs, etc. And don’t forget to check out our breadboard friendly adapters for ESP-01 modules that provides clear pin labels printed on the board to make prototyping with the ESP-01 module easier.
Read moreThe ESP8266 Wifi-to-serial transceiver is the latest and most inexpensive way to get your project connected to the Internet. If you wonder how to setup up this thing in your project, this Start-Up PDF guide from rancidbacon.com will be very helpful to you. Out of many ESP8266 modules available in the market, the ESP-01 version is the most popular one. While the headers are 0.1″ pitch, the pin arrangements are not breadboard friendly and are not labeled on board, which makes it little inconvenient for breadboarding. So you might be interested in our Breadboard Friendly Adapter (shown below) with clear
