Powering an Arduino Using the VIN and GND Pins

Powering an Arduino over its pins can be really useful. If you are trying to make your Arduino project smaller, or just don’t want to power your Arduino over USB, powering over the pins is an easy option.

Below is a step by step guide of how to do so.

  1. Make sure your Arduino is capable
  2. All new Arduino boards should be capable, but just in case, make sure that there is a VIN and GND pin on the Arduino.

  3. Get a power source
  4. In order to power your Arduino board, you need a power source of some sort. I have a variable voltage regulator, although any wall plug that outputs 5v-7v power should work fine.

  5. Connect the wires
  6. Connect the positive wire to the VIN, and the negative wire to a GND. In the case of an Arduino Nano or Uno, they put a GND pin right next to the VIN pin.

  7. Power up!
  8. If all works, you should just be able to turn on the power and the lights on your Arduino should turn on as well

It is that simple. Although, if you are having any problems at all, comment below and I will try my best to answer them.

YounginWP Website Launched

Over the past month I have been slowly working on a mostly random yet fun project. Just over a month ago I made a big change in my client work which resulted in me buying the younginwp.com domain name.

The main point of the younginwp.com website is to provide a website for my client work. I can create test sites, client portals, and show off my work. Also, if you have read the Web Hosting for Students is Awesome post, you can understand a little bit more of where my client work is going.

There is really not that much to check out on younginwp.com yet. I tried to keep the website clean, simple, fast, and responsive. I hope to write a post soon on some things I learned while making the website. I needed to go into some new territory so I am looking forward to sharing some things that I did.

Besides that, yeah, not much else. Give the website a look if you see this and feel free to provide any feedback. The website is a little experimental so feedback is welcome.

Time for bed!

Web Hosting For Students is Awesome

Over the last few months I have been trying to make some more money on my client work. Since most of my client work is for friends and family, I don’t really feel it is right to charge them that much for my work. So because of that, I have changed my approach to making money through client work.

Reseller hosting plans allow you to host multiple websites on the same account. Now most reseller hosting plans that are half decent are $200+/year. But since I am a student (#YounginWP), I was eligible to use Web Hosting for Students. Like its name suggests, Web Hosting for Students is a company that offers huge discounts for student web hosting. This means that I was now able to get a reseller hosting plan for $100 instead of $200+.

So because I have a reseller hosting plan I can charge my clients a rate of $60-$100 per year for hosting (which is about the same as a cheap Bluehost or GoDaddy plan). So if I get more then two clients (I have a lot more), then I start making money. Mind you it is not a ton of money made, but it was a wise move by my part if you ask me.

So the point of this short article was more to give a tip to young students that make websites (like ME!). Check out Web Hosting for Students and also look into reseller hosting plans so that you can make a few extra bucks.

Wassup Pi Zero

After many months of waiting I finally was able to get my hands on a Pi Zero. Considering that it was released in November 2015 and has been constantly out of stock, I am happy to finally get one.

Below are some things that you should know before you buy a of the Pi Zero.

To start, the claim of it being a $5 computer is not accurate. First of all, that is £5, which means that for us Canadians it is more like the $9 computer. Secondly, that doesn’t allot for the shipping price of £5, if you order off of The Pi Hut.

That $9 price is also just for the Pi Zero. If you want to do anything with it you will need two adapters; a mini HDMI to HDMI, and a micro USB to USB.

I just ended up buying the Pi Zero and Essentials Kit from The Pi Hut for £27. I calculated it and if I were to order the adapters separately it would of cost about the same. Not to mention that the kit also comes with an 8GB micro SD and a power adapter.

Considering all that, the Pi Zero is still significantly cheaper then it’s friend the Raspberry Pi 3, which goes for around $50 CAD.

One of the main reasons why they were able to make the Pi Zero so small is because they cut the ports down. They went from four USBs, an ethernet port, audio jack, full HDMI, micro USB, camera mounting point and display mounting point in the Raspberry Pi 3, all the way down to just a micro USB for charging, micro USB for USB devices, mini HDMI, and a slimmed down camera port. Another difference in ports is that they switched to a friction fit micro SD card slot instead of the spring one that can be found in the Raspberry Pi 2.

As for comparing specs, check out the picture below.

The Pi Zero is noticeably slower then the Pi 3 and even the Pi 2. But it can still run Raspbian perfectly fine. I noticed the performance the most when booting up. The Pi Zero took 5 to 15 seconds longer to boot up then my Raspberry Pi 3. Also with half the ram it made it hard to do anything too powerful.

For example, with the Pi Zero I also ordered the Pi Camera and the conversion ribbon. It worked ok to just take a picture off of the camera when it was hooked up to the Pi Zero, but the second I tried to set up motion detection or anything along those lines the Pi Zero would just crash.

So I guess what I am trying to say in all this is that the Pi Zero is a great board for simple tasks. But for anything that is more complicated then playing Minecraft, browsing the internet, or simple projects, it is probably best to use the Raspberry Pi 3.
