Making a Wooden Digital Clock: DIY 16×9 Charlieplexed LED grid wooden bedside clock
Thanks for sending this in Andrew Jones! Via Youtube
Hi, I really enjoyed using the 16×9 charlieplexed LED grid
and IS31FL3731 LED i2c driver in my latest woodworking project video. I made
a simple wood and LED clock using a DS3231 RTC and arduino nano and the
above mentioned LED grid and breakout board. I enjoyed combining traditional
woodworking with electronics something I’ll explore more.
Thought it my be of interest for the blog.
In this video I make a wooden LED digital clock using hand tools and a small drill press. The clock runs on an Arduino and uses an 16×9 LED panel for display and a real time clock to keep time.
This is a fairly simple physical electronics build. You only need to solder some wires together and solder the led breakout board to the LED grid, adafruit has good instructions for that: https://learn.adafruit.com/i31fl3731. Power is provided via the usb cable. I used was a cheap 40W big box store soldering iron and it worked fine. All details for the circuit diagram and Arduino sketches including the animations are in the links below. Wood used is reclaimed Aussie hardwood.

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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
