My latest digital clock is based on this video and the code found there.
It works very well but I wanted something that also gave me auditory announcements of the time. The classic way of doing this is with Westminster Chimes. Such chimes are found on most grandfather clocks as well as mantle clocks.
While the Arduino that I am using for this project is capable of producing rudimentary sounds that could resemble Westminster Chimes I opted to use an MP3 player that sounded out recordings of the chimes. This gives much better audio quality and flexibility to use whatever sound you choose to play. It also allows me to change the version of the chimes that is played by simply swapping micro SD cards.
One of my clocks is shown here. It continuously displays the time and sounds the chimes at 15 minutes, 30 minutes and 45 minutes after the hour. On the hour where it also chimes the number of the hour.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
