Introduction: Arduino (Increase Power Port Pins)

Hello friends,

This instructable is show you how to increase the number of power port in arduino board. In arduino micro-controller we have only few pins for power. For example we have only 1 port for 5V power supply in arduino uno r3. When we require many 5V port than we connect so many jumper wire and use breadboard. As a result the wires are look like a net of wire. If we connect a wrong connection of wire. Then find out a wrong wire connection is quite difficult. To overcome these types of problems follow this instructable.

Step 1: Parts Required

  1. Arduino uno
  2. Female Header
  3. Soldring iron
  4. Wire etc.

Step 2: Cutting

Now take a Female Header and cut it as much you required. In my case I cut 10 port of Female Header. In arduino have required only 2 pins, so cut all extra pins. And then a 2 pin Female Header port cut for arduino 5V and GND as shown in above image.

Step 3:

You can use simple wire for connect to each other. solder 2 side of Female Header (Left side & Right side). Now solder it. as shown in above image.

Step 4: Attached

Now attached the 2 pin Female Header on the arduino. first pin is connect to 5V and other pin is connect to GND of arduino as shown in above image.

Step 5: Finish

In the last step you connect the 10 pin Female Header on 2 pin Female Header.

The process is complete.

Now Enjoy it.

Thank you for reading.

can i power my arduino from my 5v 6A power supply?

is it safe, will it not damage it or heat it?

actually i am using this power source with ws2812b led strips behind my TV and currently i am feeding the power to arduino via TV usb port which is nuisance for me because i have to change the port everytime since there is only one usb port in my TV.

If that is a REGULATED 5V 6A power supply, and I'm hoping it is, it will be fine for powering an Arduino or other electronic devices. The 6A may be more current capacity than you need, depending on what else you have connected to it. More capacity than you need is a nice condition, like having more money than you need to pay your bills.

Don't plan on connecting a 7805 to it, not that you would need to, because the 7805 needs roughly 7.5V or above at its input. Below 7.5V and there won't be enough difference between the 5V output and the input voltage to operate the electronics in the chip.

The higher you go above the 7.5V, the greater the amount of heat (watts = voltage dropped x current) the regulator has to dissipate, which might mean a heat sink. If it gets too hot to keep your finger on, its thermal protection circuit may shut it down. There is an upper input limit around 25-30V, but you'd ordinarily try to avoid having the regulator deal with that much difference, if you could.

Thanks to give great knowledge about power loss.

Thank you. I like the idea of having a neat and convenient place to plug things in, but you might caution that having more places to plug in doesn't "create" more power. All of the power has to come either through the USB connection you're using or the Arduino's on-board regulator. Both of these are quite limited in capacity, particularly the on-board regulator.

Personally, I would be reluctant to add a total load greater than two or three LEDs to this connector, for fear of overloading the regulator and having it shut down. That protects the regulator, but might result in an intermittent failure that will be terribly difficult to troubleshoot. .

6A is large amount of current. You can use 7805 for limiting the voltage and 7805 have a quality to limiting current at 1.5 A. you can use 7805 in USB power circuit.

Clever hack! That goes in my notebook... Keep bringing these out!

I did something similar, to rows of pins each rows soldered together. It looks better, and I have the same amount of 5V and GND
