4×1 WiFi Wireless Antenna Switch
https://www.electronics-lab.com/4x1-wifi-wireless-antenna-switch/
Horacio Bouzas published a 4 way WiFi antenna switch: I started playing with electronics back when I was 10 years old in Argentina, where I grew up. Then I got my ham radio operator license when I was 16 years old and I was very active in the ham club and on the air. It […]
ESP8266 + Attiny85 + DHT22 Temperature/Humidity Logger
https://www.electronics-lab.com/esp8266-attiny85-dht22-temperaturehumidity-logger/
by guibom @ github.com: Basic ESP8266 + Attiny85 + DHT22 Temperature and Humidity logger. I’ve made this to experiment a bit with the ESP8266 wifi module, and hopefully make a remote sensor that posts the data to my server. I wrote the code to work with both an atmega328 and a attiny85. The mcu sleeps in between […]
Milk in Fridge – Internet of Things
https://www.electronics-lab.com/milk-in-fridge-internet-of-things/
by samsungite @ instructables.com: I think that one day, all food cupboards & fridges/freezers will be smart. All products will have an RFID or video recognizable label which will update a list of product usage. Your local supermarket will gather this information & replenish your products as required – who knows ?? Milk in Fridge – […]
How to Control Your ESP8266 From Anywhere in the World
https://www.electronics-lab.com/how-to-control-your-esp8266-from-anywhere-in-the-world/
by Rui Santos @ randomnerdtutorials.com: The most common questions I get about the ESP8266 WiFi Modules are: “Is it possible to control my ESP8266 from anywhere in the world?” and “How can I control my ESP8266 from anywhere?”. I’m happy to announce today that I have a solution for that problem. With the new version of […]
Posting a Tweet with the ESP8266
https://www.electronics-lab.com/posting-a-tweet-with-the-esp8266/
by Rui Santos @ randomnerdtutorials.com: In this project you’re going to post a Tweet with an ESP8266. The goal of this project is to show the endless possibilities that this $4 WiFi module offers when integrates with a free platform that I’m about to show you. In order to accomplish this task you have to sign […]
Arduino-based “Analog” slow cooker controller
https://www.electronics-lab.com/arduino-based-analog-slow-cooker-controller/
Dan Ternes blogged about his Arduino-based controller for analog slow cookers: With the AC power control figured out, I considered the User Interface. I opted for something simple. The Adafruit RGB LCD Shield would work well as it had both a display and buttons built in. Sure, I could have beat this project about the […]
ESP8266 Weather Station with Arduino
https://www.electronics-lab.com/esp8266-weather-station-with-arduino/
by ohneschuh @ instructables.com: I read about the ESP8266 first in March this year and I didn’t know what to do with. And now I’m really fascinated how easy the connection of an Arduino to the Internet can be. Like others I set up a weather station on a breadboard first and sent data to thingspeak.com. […]
ESP8266 MQTT battery monitor project
https://www.electronics-lab.com/esp8266-mqtt-battery-monitor-project/
Steve’s latest project, a wireless MQTT battery monitor: This board uses an ESP8266 (ESP12), a Texas Instruments INA226 I2C voltage and current monitor, and a Texas Instruments LMR12010X buck converter. This board is designed to wirelessly monitor 12 volt batteries and power supplies using an external current shunt resistor. The voltage across the shunt resistor […]
WIFI Mains Power Dimmer / Switch

MAINS Power Dimmer / Switch Module project by Tracker J: Now it’s about time to talk also about what many of you has asked for: DIMMING! It’s a total different story, little bit complicated but, as you will see, not so hard to understand. General considerations: There are several types of dimmers generally available. These […]
