How to Get Started with Arduino

Buy the Arduino UNO (R3 at the time of this writing). This is the “most standard” version of the Arduino that I’ve come across. The Arduino IDE works perfectly via USB and most shields that you come across will be physically and electronically (5V logic) compatible. I would start with the Arduino UNO R3 to develop on and then get a smaller or more energy efficient version when finalizing a working prototype.

The classic lighting of a LED connected with a 220Ω resistor is always a great way to start. But I think a great first project that will cover the basis of A LOT of future projects is to read input from a sensor of some sort and then output a value to a LCD display.

As a first project, I would recommend a simple, but useful temperature and humidity read out, a thermo-hygrometer with a basic 16×2 LCD display. It’s easy to be overwhelmed by all the various concepts involved when starting with electronics, but you really don’t need to understand too much to get something working. You can always dive deeper once you get a few projects under your belt.

Materials

  • Arduino UNO R3
  • Breadboard
  • 4x AA battery holder or similar 5V power supply
  • Temperature and humidity sensor DHT11
  • 16×2 LCD display

How to Remove Proudly powered by WordPress

In the root folder of the theme that you’re using, find the footer.php file.

The path for this file might look like this:
wordpress/wp-content/themes/twentynineteen/footer.php

Open this file in your favorite text editor and remove this line:
printf( __( 'Proudly powered by %s.', 'twentynineteen' ), 'WordPress' );
I would search for “proudly powered”.

Since it’s hard coded into the theme, there are no settings you can tweak from the admin GUI to make this go away.

How to Setup WordPress for Basic SEO

On the left hand side, hover over Settings and click on General
Change Tagline to something related to your site (I recommend the “type” of business or individual such as Chinese buffet or basket weaver whatever may be the case).
Click “Save Changes”

Title and Tagline shows up on the homepage and on top of every post, category, etc.

On the left hand side, hover over Settings and click on Permalinks
Change Permalink Settings to Custom Structure and enter:
/%category%/%postname%/

By default your permalinks will look like:
http://huigardens.com/2018/11/13/hello-world/

With the new permalink structure, it’ll look like:
http://huigardens.com/uncategorized/hello-world/

Of course that will look better once you name your categories properly.

How to Install WordPress?

What Do I Need for WordPress?

Web Hosting with PHP and Database (MySQL or MariaDB)
How to setup own domain and web hosting is covered in another article.
For the purpose of installing WordPress, I'll assume you've already got web hosting setup.

Download WordPress
https://wordpress.org/download/

Upload WordPress .Zip File to Web Space
Via FTP or some other means just get it transferred.

unzip wordpress-x.x.x.zip
The above command will create a directory named "wordpress".

To move the contents of the "wordpress" directory to one level up:
mv wordpress/* ./

Remove the now empty "wordpress" directory:
rm -fr wordpress

Go to your domain and you should see the WordPress Setup Screen
Select English and click "Continue".

You will need the following database information from your web host before proceeding:
Database name
Database username
Database password
Database host
Table prefix (good practice to do this even if you'll only have one WordPress install for now)

Click "Let's go!".

Database name
Database username
Database password
Database host
Table prefix

Click "Submit".

If the database credentials provided worked, you'll see this screen saying that it can communicate with the database.

Click "Run the installation"

Enter the following information:
Site Title e.g., Hui Gardens
Username
Password
Your Email
Search Engine Visibility (I recommend NOT checking that checkbox to allow search engines to index your site
otherwise how will people find you? Don't put things online that you don't want people to find.)

Click "Install WordPress".

If all goes well, you'll see the Success! screen

Click "Log In".

This will take you to yourdomain.com/wp-login.php
You can come back to this page by this URL as well:
http://yourdomain.com/wp-admin

That's IT! Log into your fresh WordPress installation and start writing.

I'll go over some basic WordPress SEO setup in another article.
