This is the development repository for the Word Clock, powered by Arduino, a cheap DCF77 receiver module, and almost two meters of WS2812B LED strip. Uses the brilliant FastLED library to control the ...

A Proof Of Concept attempt to get accurate(ish) time from an NTP server. The result gives the time within +-10 milliseconds of the time as referenced to the DCF77 time signal from Frankfurt, Germany.

Time synchronization for wireless sensors is important for a proper interpretation of measurements, particularly for acceleration measurements to estimate mode-shapes. This paper presents a new time ...

Last year, Seeed Studio introduced Air602 WiFi module, a competitor to ESP8266 based on Winner Micro W600 Arm Cortex-M3 microcontroller and selling for $1.90. The module was clearly optimized for cost ...
