Hi from Italy
Although many watches are created binary, my project was inspired mainly to this:
http:// http://www.instructables.com/id/LED-Binary-Clock-1/, very smart and funny.
I tried to improve the design and to add something personal.
I think it's a good result at the end.
The project is not difficult, requires patience, it requires a little knowledge of electronics and the use of Arduino.

Ok, check out the video and if you like it lets start!

Luigino.jpg
Luigino scheda.jpg
-n.1 IKEA frame called "Ribba" 13x18 cm
-LED to mark hours and minutes (You have seen the first images of the LEDs that there are different colors, but of course you can change them as you like, now is the reference of the project.):
n.8 green 5 mm
n.3 red 5mm
n.2 yellow 5 mm
-LED to light the words "Hours Minutes"
n.7 white 5mm
-LED to light the numbers 1/2/4/8
n.4 pink 5mm
-LED to light the words "binary clock"
n.4 pink 3 mm
-n.24 Resistor 220 ohm (for 5mm led)
-n.4 Resistor 150 ohm (for 3mm led)
-Cartonboard thicker to make LED holder
(we will Insert the cartonboard between the glass and the bottom of the frame supporting)
-Some acetate (4-5) sheets (for inkjet or laserprint) to create the mask
-a flat wire 26 wire
-3 micro button to set hours and minutes and on/off
-A small piece of prototyping PCB to make the shield (see later)
-Some double strip
-n.1 Arduino Uno/2009 or clone or self made. I've used one Luigino assembled by me
-Power supply 6V 500ma or other Arduino compatible.

Great, it looks like a bought clock

Can u explain about micro switch connection between led and arduino
Cello62 (author)  sibi.20092 years ago
Hi
All i think has explained above. What isn't clear? All the micro switch have two pin, one is connected to an Analog pin of Arduino (see what) and one to GND. If you have a question again let me know. Thanks
Regards
ok ok thanks.......i also have problem with opening the code file
Cello62 (author)  sibi.20092 years ago
Is a web site problem, if you have installed Arduino IDE correctly try to rename the file as .ino or .pde , the last methods is to copy and past the text into an arduino clear sketch
Regards
thanks for your help problem has been solved
Whether v need to connect the switch with pull down resistor as given in this page

Cello62 (author)  sibi.20092 years ago
not necessary in this case isnt the same like your tutorial
Nice! I can see that you have successfully completed your project.
Cello62 (author)  Emiliano Valencia2 years ago
Yeah
Thanks for the advice, I just tried to do something that is also visually beautiful.
Hey, I built a new version of my clock, be sure to check it out.

that is really beatiful, I made it, but I have some problems with the software. effectively, my clock is low, I lost 7minutes in 3days! have you a solution? have you modified the soft? thx for all
Cello62 (author)  livoyema2 years ago
Hi
Ty for reply
No, i'm sorry, as explained there is a version 12 hours and at 24, I used the version in 24 hours and is perfect.
Sometimes there can be problems if there are changes in Arduino voltage double check if the power supply is ok.
Thx for responding so fast!
My power supply is 12V for my arduino, but I don't know how it can be the problem?
you have no delay problems on yours?
excuse me, I'm french, and my english is not fluent!
May be I can see inside the following boucle to send lasTick by serial port.
"if (millis() - lastTick >= 1000) {
lastTick = millis();
second++;"
Like that, I'll see if it is really 1000 between two values.

>>Thx for responding so fast!
I'm in Italy, yours email comes faster here....;-)

>>you have no delay problems on yours?
No, i'm sry
I told you about power supply is important because it is stabilized by 7 to 12 volts, power surges can cause delays.

That is a beautiful rendition of a LED clock - I love the care you have taken in making it.

:-)

Never like yours, I can improve .. thanks

Really beautiful, and much easier to read than I thought it would.

Thanks very kind
