“Hello guys and welcome to a new instructable. Today we will make a simple arduino watch using DS3231 and Nokia 5110 Lcd. This watch will of-course show you time but also it will also show date and temperature. Most of …
“A while ago, I mentioned to some of my co-workers that is it possible to make a simple split-flip display. (I actually made one with cardboards and toothpicks, and it looks…not pretty.) A guy digged out this clock set …
“Matrix clock with scrolling time, date, day of week, temp, humidity and event notifications. I wanted to build upon the clock logic I developed for the previous clock but put it into a more visible format. This clock is built …
“Project: ILC1-1/8L Clock This project was undertaken to make use of the ILC1-1/8L VFD tubes, otherwise the project uses standard components and provides the display with time, date, Chimes, pressure, humidity, temperature centigrade, and Fahrenheit. Using …
