Wow, Sandpapering the LED's seems a little harsh, and it doesnt limit the current the LED wants to pull out of the Arduinos I/O pins. Remember an LED at full bright will pull as much current as the source can provide, even to the point of burnout. I really suggest in future using a current limit resistor in series with your LEDs ( They and your Arduino will be much happier ).Have a look in Instructables, there are several really good decriptions of why to use a resistor and how to calculate the optimum vale.I must say though, this is a cool little project. Well done on what you have created.
Nice addition to your list. I wonder how many ways a binary clock can be realised.Terry
I have a question. In the breadboard diagram the Hours connection seem to be reversed to the Sketch. E.g Hour 1a is Arduino 26 on the drawing but 22 in the sketch. Hour 5 Is 22 on the drawing but 26 in the sketch.Is the drawing reversed for the hours connections?RegardsTerry
Ty Tiziano. Just wanted to clarify before I start the build. This is a great instructable. ?
Thanks to Doug for this awesome instructable and his assistance with all my queries :)
I would suggest adding some current limiting resistors to the LED's. At full current I would think the Arduino is going to suffer.Something around 330R would provide current limiting and still provide good illumination.
This is the picture frame version, no seconds. Whole clock assembled on stripboard and mounted on a deep picture frame.
Hey Cwik, Here is a pic of my clock. The time set controls are on the back. I have also built a couple without the meter and installed them in deep picture frames. They all work beautifully. Thanks for the great Instructable> :)
Heya Stregoi, Any chance you can provide a schematic of the arduino pinouts and the RTC connections aswell as a complete sketch.
Again Thanks for your info. I think I have it sorted now. I am planning a build around a homemade controller. I have attached my layout :)Hopefully the next pic will be a finished unit :)
Tnx for the prompt answer Sir. So if I understand, pin15 is only a label for the sketch, The physical pin is Analog 01 (nano 20). Pin 11 is not labelled in the drawing so I assume it is the actual Digital 11 on the nano.Sri for the questions, I am still quite new to Arduino :)Terry
Hello Mr Fid, Love this project but have a question.In your connection drawings the switch connections show a pin number and a number in brackets. I assume the bracket is the arduino designation e.g. A1 is Analog 1 etc, but I dont follow the pin number reference. e.g. Set hours + = pin 15 (A1) but I see A1 as Nano pin 20 (or 328 pin 24)Can you clarify the pinouts. I suspect I am reading things wrong.Regards Terry
Hi Marc, Great project :)Just one question, how do you set the time once its powered up?Cheers Terry
A true thing of beauty, my next project. It will place alongside my Word Clock and my Binary Clock, Main aim is to confuse my family lol. A lovely instructable :)
Heya Cwik. TY for posting this project. I have been looking for a binary clock to build, and while I have found many, this one is simply superb. The analog seconds readout is brilliant. This is now my new project.
