binary-clock

This is my first hardware project. After learning how to use the arduino, I decided to try to make my own binary clock. I designed the clock, wrote the firmware, created the schematics and board layout, and etched the PCB.

BOM

• 1x Atmel ATMega328
• 2x 10uF Capacitor
• 2x 22pF Capacitor
• 10x 220ohm Resistor
• 1x 1kohm Resistor
• 2x 10kohm Resistor
• 1x 16Mhz XTAL
• 3x Push Button Switch
• 1x Power Jack
• 1x 5v Regulator

Design

Most binary clocks available use 2 bytes for each hour, minute, and seconds and I did not like that approach, so I designed my own clock. However the clock does not have an AM or PM indicator.

Hour		Minute
on:8, off:0	on:4, off:0	on:32, off:0	on:16, off:0	on:8, off:0
on:2, off:0	on:1, off:0	on:4, off:0	on:2, off:0	on:1, off:0

Example: 10:35

Hour		Minute
on	off	on	off	off
on	off	off	on	on

Hour: 8 + 2 = 10 Minute: 32 + 2 + 1 = 35
