If a screen is heavier or larger than specified in table 1, it should use a larger variant from the table, for instance, a 30-in LCD TV weighing more than 50 lb (23 kg) would need to use a part F mount.

The rounded rectangles and distances (see below) do not apply towards the edge, except that the surface on the screen need not touch the bracket beyond them.

LCD, or Liquid Crystal Displays, are great choices for many applications. They aren’t that power-hungry, they are available in monochrome or full-color models, and they are available in all shapes and sizes.

Waveshare actually has several round LCD modules, I chose the 1.28-inch model as it was readily available on Amazon. You could probably perform the same experiments using a different module, although you may require a different driver.

Open the Arduino folder. Inside you’ll find quite a few folders, one for each display size that Waveshare supports. As I’m using the 1.28-inch model, I selected theLCD_1inch28folder.

Once you do that, you can open your Arduino IDE and then navigate to that folder. Inside the folder, there is a sketch file namedLCD_1inch28.inowhich you will want to open.

Unfortunately, Waveshare doesn’t offer documentation for this, but you can gather quite a bit of information by reading theLCD_Driver.cppfile, where the functions are somewhat documented.

This library is an extension of the Adafruit GFX library, which itself is one of the most popular display libraries around. Because of this, there isextensive documentation for this libraryavailable from Adafruit.  This makes the library an excellent choice for those who want to write their own applications.

Here is the hookup for the ESP32 and the GC9A01 display.  As with most ESP32 hookup diagrams, it is important to use the correct GPIO numbers instead of physical pins. The diagram shows the WROVER, so if you are using a different module you’ll need to consult its documentation to ensure that you hook it up properly.

The GC9A01 LCD module is a 1.28-inch round display that is useful for instrumentation and other similar projects. Today we will learn how to use this display with an Arduino Uno and an ESP32.

As a recruiter, that means this little round image is your first chance to make a good impression on candidates — and it"s a key element of your recruiter brand.

Where you take your picture matters. You don’t want anything to distract from your face, so a simple background can help ensure that you’re the focal point.

LinkedIn now offers six filters that you can apply to your profile picture, each of which will give your photo a slightly different look and feel. Think carefully about what kind of mood you want to convey, and don’t be afraid to play around to see which filter looks best. The Spotlight and Classic filters, for example, can make your image look more polished and sharp.
