Not once did you tell us what voltage you are applying to the input power jack. Why is that?Paul
Hi Paul, there is a note just right below the cable of the input power jack, its 5V via a voltage regulator. i read that UNO can do 6-20V, and safe margins are 7-12V as input. i already burned 2 boards for whatever reason and the dc jack input no longer works. so i am using a 5V power jack input on the new board.
i couldnt measure my battery mA just volts so
And the current the onboard regulator can supply is totally insufficient to drive 60 LEDs. You need 3.6 Amps to drive that many LEDs.
The Uno can run on 7-12 volts thru the power jack because it has an on-board 5 volt regulator to power the processor. If the DC power jack no longer operates, it's because the regulator has died.If you connect your 5 volt power to the 5 volt pin of the Uno board, that will power the Uno directly, No regulator.There is NO 5 volt power jack on any of my Arduino boards. There are 5 volt pins. Is that what you are using?Paul
Hi,This diagram may help, feel free to change, comment, criticize.Tom...
I will get a look at this as i dont understand any of the components you used.
But it WONT work if i do this from daylights cable.
when i am powering the ardunio from usb laptop, everything works fine.
These were all the components you used in the original diagram, plus resistors and capacitors that you should have used.What are "daylights cable"?The L7805 will not be able to supply enough current to light all those LEDs at full brightness, so when you say:-You are not testing them correctly as there is no way you can get that much current from a USB socket. The maximum from a USB socket is 500mA. You will have to keep the brightness down or not light all the LEDs at the same time to stand any chance of working.
Hi,Can you post a picture of your project, so we can see your component layout?Can you post your code please?Thanks.. Tom... PS. If you cannot understand the symbols, then don't attempt the project until you can.
