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
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
