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!

Step 1: List of materials

-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.
<p>I built your clock and it worked perfectly.Then I decided to build another one only this<br>time displaying seconds as well as minutes and hours. It work perfectly as far as the time goes but<br>it has one problem that I can&rsquo;t figure out for the life of me. Maybe someone here who has built this clock<br>might have an idea.</p><p>Here&rsquo;s the problem. I<br>am using standard 5mm diffused LEDs.The LEDs<br>for the hours and minutes work fine. For<br>the seconds, from 1 second up to 10 seconds, the LEDs light normally but when<br>it gets to 20 seconds, that LED lights but is quite dull. When<br>it gets to 30 seconds both the 10second and the 20 second LEDs light<br>normally. When it gets to 40 seconds,<br>again, that LED is quite dull but once it gets to 50 seconds, the 10 second and<br>the 40 second LEDs both light normally.</p><p>All of the resistors are the same at 220 ohm.Anyone have any ideas as to what might cause<br>this problem?</p>
<p>sir may i ask on how did you solder or how did you put the flat wires in the pb or in arduino thanks</p>
Oh,yes thanks.. That was my Issue.
<p>New to arduino, I loaded the sketch to a Nano. I can get the secondary lights to work, but only pin 1 seems to be flashing in some sort of fashion. Is there something I need to change in the sketch? </p>
<p>Hey,i got a problem:</p><p>If i&acute;ve already made the Arduino Shield,but where to connect the 26 pin flat wire at the Arduino?(maybe i&acute;m dumb^^) (Sorry for my bad english..) I hope someone can help me.. </p>
<p>Did you read the instructables? </p><p>LED1-LED2-LED3-LED4 to ARDUINO DIGITALS PIN1-PIN2-PIN3-PIN4</p><p>LED5-LED6-LED7 to ARDUINO DIGITALS PIN5-PIN6-PIN7 </p><p>LED8-LED9-LED10-LED11 to ARDUINO DIGITALS PIN8-PIN9-PIN10-PIN11<br>LED12-LED13 to ARDUINO DIGITALS PIN12-PIN13<br>LED14/LED15/LED16/LED17/LED18/LED19/LED20/LED21/LED22/LED23/LED24/LED25/LED26/LED27/LED28</p><p>to ARDUINO DIGITAL PIN 0 (all toghether)</p>
<p>Do i need to steal a supermarket basket? :) haha</p>
<p>Shure you need to :D haha </p>
<p>I finally made it... with some small modifications, and I credited your Instructable.</p><p>http://www.instructables.com/id/Arduino-Binary-Clock-2/</p>
Great job! Very nice. Thanks for sharing
<p>I am trying to do a simulation before making this to make sure I am doing it right, but the leds keep blinking no matter what I do. Right now I don't have the hour and min leds given that they really don't need coding. <a href="http://123d.circuits.io/circuits/559138-binary-metric-clock" rel="nofollow">http://123d.circuits.io/circuits/559138-binary-met...</a> Just click &quot;start simulation&quot; </p>
<p>I made it after your good instruction. I made also a small circuit for the atmega 328. I soldered the led the other way, cathode (negative -short leg) to GND and the anodes (positive-long leg) to the to digital pins, didn&rsquo;t read carefully, so I had to switch digitalWrite in the sketch.</p>
Grazie. gentilissimo! E complimenti per i tuoi progetti di orologi. Sono bellissimi.
ciao, non mi &egrave; chiaro&quot;a layer of gray and a white matt&quot; te lo chiedo in italiano perch&eacute; in inglese non ho capito :-(. <br>Sono due ulteriori strati? Quello bianco &egrave; la carta da disegno opaca, mentre quello grigio?<br>grazie
Ciao<br>In sostanza devi fare in modo di evitare che la luce dei led si &quot;diffonda&quot; e si concentri solamente solo sulla lettera da illuminare. Per ottenere questo io ho adottato del bianco opaco, che limita la diffusione, e uno o pi&ugrave; strati di grigio che smorzano l'intensit&agrave;, fai le prove comunque. A presto
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
<p>The loop is losing time. Imaging that lastTick is on 901 and the next loop() doesn't come around for 101 ms, then you'll be at 1002ms by the time you reach the if condition. What happens to the 2ms? They are lost. It can be even worse; you are at 999ms and the next time takes 101ms, you would end up at 1100ms, losing a whole 100ms!</p><p>Also, since you are calling millis(); twice in the original, there is a chance that the second call is further forward than the first comparison. </p><p>Try this fix:</p><p>int temp = millis();<br>if (temp - lastTick &gt;= 1000) {<br> lasteTick = temp;<br> second++;<br>}</p>
<p>I saw online that when creating a clock this is &quot;normal&quot; because of voltage difference and things like that... there is a &quot;Real Time Clock&quot; module that exists that makes sure that the time stays accurate, I don't know how it works exactly, but it could fix your problem... but hopefully you fixed your problem in the last 2 years ;)</p>
Hi<br>Ty for reply<br>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. <br>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! <br>My power supply is 12V for my arduino, but I don't know how it can be the problem? <br>you have no delay problems on yours? <br>excuse me, I'm french, and my english is not fluent! <br>May be I can see inside the following boucle to send lasTick by serial port. <br>&quot;if (millis() - lastTick &gt;= 1000) { <br> lastTick = millis(); <br> second++;&quot; <br>Like that, I'll see if it is really 1000 between two values. <br>
&gt;&gt;Thx for responding so fast! <br>I'm in Italy, yours email comes faster here....;-)<br><br>&gt;&gt;you have no delay problems on yours?<br>No, i'm sry<br>I told you about power supply is important because it is stabilized by 7 to 12 volts, power surges can cause delays.<br><br>
Great, it looks like a bought clock
Can u explain about micro switch connection between led and arduino
Hi<br>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<br>Regards<br>
ok ok thanks.......i also have problem with opening the code file
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<br>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 <br> <br>http://arduino.cc/it/Tutorial/Button
not necessary in this case isnt the same like your tutorial
Nice! I can see that you have successfully completed your project.
Yeah<br>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.<br><br>http://www.instructables.com/id/LED-Binary-Clock-20/
That is a beautiful rendition of a LED clock - I love the care you have taken in making it.<br><br>:-)
Never like yours, I can improve .. thanks
Really beautiful, and much easier to read than I thought it would.
Thanks very kind
