Powering an Arduino Without Wires





Introduction: Powering an Arduino Without Wires

Wanna ever thought of powering an Arduino without wires? Check it out.

Step 1: Get These Stuff

You need these for this.

2.Battery Holder (6v)
3.4 x AA batteries

Anyone try it with a 9v battery. If works, please post a comment.

Step 2: Powering

Put in the batteries in the holder and hold it according to the pic.

Do not hold it the other way. Arduino wont light up then.

Step 3: Place

Place it accordingly.

Remember, it must touch the both ends of the ICSP headers.

Step 4: Ta-Da

Ta-Da , the Arduino lights up.

So you have learnt a silly process to power up an arduino without wires.

For projects, tape it to avoid power failure.

Comment? Suggestion? Problem? Please post in comments.
Feel free to send me a message.

    I don't care if the words were included as part of urbanization. I refer you to proper English. Period. Learnt is NOT a word. Period.

    My comment is that the word is LEARNED, not learnt.
    Otherwise, neat trick!
    I would also do one other thing.
    The Arduino processor can heat up a lot when it has more than 5V going into it.
    It will run on just about anything between 3 and 5 volts though, so take out one battery, and replace it with a dummy cell made out of rolled up tinfoil. This will reduce the voltage to 4.5V and save possible damage to your ATmega328 chip.
    Remember, the power that goes into the ICSP header does NOT go through the 5V regulator on the board the way that power going into the power input jack does!

    Not a problem. The last thing you need is to have people coming back here screaming that your "trick" burned out their ATMega processor.

    I actually print warnings right on my circuit boards that have the "Regulator Bypass" function that there is a risk of damage to the processor if using more than 5V on an unregulated board.
    The reason I have a regulator bypass is for people that do want to operate their circuit on batteries. The regulator is a great hinderance when running on less than 5.5V input.

    dont remove coments ,ur fre 2 express ur views

    The comments needed to be removed because the conversation was not constructive, somewhat rude, and there was no value added. It was very close to violating the "be nice" comment policy below the comment box.

    This is the worst method of powering arduino. 4 batteries like these give 6V which is too much for ICSP header. 3 would be better. 9V baterry will surely destroy your arduino. But only if you're too poor to buy 9V baterry socket. If not, you can connect it to Vin pin. It gets regulated...

    agreed 9V would kill it.. But if you use rechargeable AA's, that would be 1.2V each for 4.8V, which the 328P will run on just fine, as long as you don't have a ton of sensors. You could also use slightly used alkalines to have less than 6V for more safety, which is likely what this instructable is doing.

    Or you could use a voltage divider...
