The Wemos D1 or you can use a voltage regulator circuit thatĪs you can see from the schematic the wiring The unit can be powered from a USB cable to In addition you will need a 1K resistor, aġ0K (a 50K or 100K will work, too) and an 8 ohm speaker. The processor is a Wemos ESP8266 that canĭramatically by adding a red filter. To make these files I changed the Tempo in a sound editing program The sound files that I used are availableĪ shorter version is here: mp3-shorter.zip There are 6 sound files for the WestminsterĠ001.mp3 - the chimes for the quarter hourĠ003.mp3 - the chimes for the three-quarter hourĠ006.mp3 - the hour chime with a long trailing sound at the end This page also suggests where it can be purchased.įiles for the MP3 player reside on a micro SD MP3 player that stores sounds on a micro-SD card. It is the DFPlayer, an inexpensive, high quality I have used the MP3 player that is used in this project many Minutes after the hour and on the hour where it chimes the number of This gives much betterĪudio quality and flexibility to use whatever sound you choose toĬontinuously displays the time and sound the chimes at 15, 30, 45 Resemble Westminster Chimes I opted to use an MP3 player that Project is capable of producing rudimentary sounds that could While the Arduino that I am using for this

Grandfather clocks as well as mantle clocks. TheĬlassic way of doing this is with Westminster Chimes. That also gave me auditory announcements of the time.

It works very well but I wanted something Many thanks to John Rogers who posted the video. The larger one is binary and the other two I have built a number of clocks over the years starting with aīinary coded decimal kit that looked something like this whenĭigital clocks that synchronize with the time servers that can beĪccessed over the Internet.
