GPS or WiFi (NTP) clock using a PIC and an LCD screen

摘要

This simple project uses either a GPS module or a WiFi-equipped microcontroller module to give an accurate time and date display on a 16x2 alphanumeric LCD. You can use just about any GPS module, as it extracts the time and date from the standard NMEA serial stream. Or you can use an ESP8266 microcontroller module with WiFi to emulate a GPS module while getting the time and date from internet time servers using NTP.
