Elektor Project: Wi-Fi for LoRa Switch


https://www.electronics-lab.com/elektor-project-wi-fi-for-lora-switch/

Clemens Valens @ Elektor Labs writes: We published a remote-controlled switch in the March/April 2020 edition of Elektor magazine. It had state feedback and communicated using LoRa. Because it was housed in a waterproof IP66 enclosure, it was suitable for outdoor use. It was also a modular project with the relay and power circuitry on […]

When you are waiting for a very important letter to come, it’s really bothersome to go and check the post box again and again. The problem gets worse when you are not at home and anxiously thinking if the letter arrived or not. Well, now IoT or Internet Of Things is your savior. Following this […]

How to Upgrade Your ESP8266 SPI Flash to 4MB


https://www.electronics-lab.com/upgrade-esp8266-spi-flash-4mb-one/

ESP8266, the well known WiFi module contains an ESP8266EX SoC IC and an external SPI flash. This external SPI flash is used together with ESP8266EX to store user programs. The supported size of flash by ESP8266EX is up to 16MB but some of ESP8266 modules contain flash chips with low storage capacity like 512KB. In […]

ESP8266-based Clock Synchronized With Network Time Service


https://www.electronics-lab.com/esp8266-based-synchronized-network-time-service/

Thanks to Internet, the problem of time shifting in embedded and connected devices was solved using time synchronization over Internet. National Institute of Standards and Technology provides a service called Network Time Service (NTS) over the Internet. The project of ESP8266-based clock, published on embedded-lab, is going to demonstrate how to make a benefit from […]
