While the build in GPS works well, it can be an issue within well insulated home to receive GPS/ DCF signals from the outside. Hence the wish to add NTP with the needed hardware and code to get a ...

Project goal: Create a super-accurate (<1ms drift per year) standalone 7-segment LED clock whose time stays accurate and "sets itself" without access to the Internet or a host computer (i.e., without ...

At the beginning, I wanted to build a 7 segments clock with Arduino . . . I found on Internet the little TFT screens (2.2’) able to display anything at very low price. But what to do first ? This ...

PLEASE NOTE:- In some editions fo the Magazine (GB, DE), the Temprature sensor is listed as a DS1820 - This should read DS18B20. The DS1820 is an old part and does not function correctly in this ...

[Toni] has been playing around with NTP, the Network Time Protocol. This allows the alarm clock build to keep very accurate time by synchronizing with an NTP server on the Internet. The project serves ...

Maker Michael Klements has built a unique electromechanical clock using a little Arduino hardware, code, and 28 servos, which tilt panels to reveal the correct time in digital format. As the time ...

Making a clock with a common microcontroller like an Arduino isn’t very difficult. However, if you’ve tried it, you probably discovered that keeping track of wall time is difficult without some ...
