How to build a wooden digital clock powered by an atmega168 (arduino) with a built-in alarm and games.
I first thought about making this when I saw an LED clock covered by a wood veneer . I liked it when I saw it, until I saw the price. This is when I decided to build my own, I wanted it to build it for much less, from solid wood and play games!
Step 1: What You Need
– 4, 18″ x 4″ x 1″ wood planks (I went with Maple)
– 85 Red LEDs
– 85 Green LEDs (Optional)
– 1 4 to 16 pin Demiltiplexer
– 15 NPN transistors (such a 2N3904)
– 1 ATMEGA168 Microcontroller (or Arduino)
– 1 20 MHz Crystal
– 1 5 Volt Regulator
– 2 220uF Capacitors (for power spike leveling)
– 1 Old Pocket Radio
– 2 1/8″ Audio Jacks
– 1 5-9V DC wall adapter
– 1 (or more) Old Game Controller(s)
– 4 3-1/2″ Wood Screws
– Solid Core Wire (easier to work with)
– Hot Glue Sticks
– White Glue
– Sand paper
For the game controller I use an Atari 2600 joystick (or even paddle if you re-program), but it is also compatible with with a Sega Master System Controllers, Atari 7800 joysticks (theoretically) or even Sega Genesis Controllers.
– Drill press
– Flat End Hobby Tool Bit
– Soldering Iron
– Hot Glue Gun
– Miter Saw
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.
