Thanks to Marty for sending in his great clock project! He writes:
This clock/day/date project is based on the Arduino MEGA 2650, using an Adafruit 32 x 32 RGB LED Panel. Displays digital day, date and time display, alarm (continuous or pulse) with adjustable snooze period, snooze limits, configurable auto Daylight Saving and Standard time adjust, and clock fine tuning/accuracy adjustment.
Extensive use is made of Adafruit’s Graphix and PanelMatrix Arduino libraries.
Some planned enhancements include: Temperature compensation adjustments to improve accuracy, auto display dim and restore based on time, ability to turn off/disable the alarm after 15 seconds, and additional sound effects (i.e. seconds tick, and hour/minute repeater sounds), and auto holiday message displays for New Years, Valentine’s Day, Mother’s Day, Halloween, Thanksgiving and Christmas.
Because the MEGA 2560 is being used, this project allows for many more options which can be added including color customizations/selection and the ability to add other sensors and associated data displays (i.e. like temperature, barometric pressure, relative humidity, etc. or other info or time adjustments from the web).
32×32 RGB LED Matrix Panel – 5mm Pitch: Bring a little bit of Times Square into your home with this sweet 32 x 32 square RGB LED matrix panel. These panels are normally used to make video walls, here in New York we see them on the sides of busses and bus stops, to display animations or short video clips. We thought they looked really cool so we picked up a few boxes of them from a factory. Read more.
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.
