Arduino Shields - a way to visualize your data

In this category you will find a wide selection of the best Arduino Shields, which work particularly well with other components; we have chosen them for you because we are aware of the fact that information visualization is very important when you build more advanced projects and also when you start your adventure with Arduino.

It's worth noting that among the most popular Arduino direct communication methods are two types of devices - Arduino keyboards and displays. They will prove to be extremely useful, especially if you do a lot of programming and create a device that is compatible with applications for mobile phones or computers. Most of the LCD displays have a touch screen with a keyboard. This solution is most commonly used because it offers high working efficiency, looks good and takes up little space.

How to use Arduino Shields with LCD displays and keyboards?

Once you have chosen the appropriate Shield that meets your expectations, you still need to ensure its correct configuration - it is not just a display, but a fully programmable device that is compatible with other elements. What should you do to take advantage of the amazing convenience offered by these unassuming overlays? Using and configuring the display is easy thanks to the free Arduino library "LiquidCrystal". Then you can just sit down and write a few lines of code - with this simple action you can, for example, design the CNC machine's control menu that can be navigated via the keypad, which you will also find on the shield.

The basic version of the LCD built into Arduino Shield consists of two lines of 16 characters. In practice, of course, this means that we can present on such a display information consisting of up to 32 characters. The button keyboard communicates with the Arduino through a resistor divider connected to one of the inputs of the analog-to-digital converter. Each key on the keyboard is detected by the voltage applied to the analog input of the microcontroller.

What are the performance conditions?

The Arduino Shield with an LCD display and a button keyboard requires a voltage of 5V. This power supply is necessary to ensure proper screen backlighting and contrast to facilitate reading of information. Since powering the Arduino through the USB port can cause the voltage to fluctuate and constantly change, the display can fade or become unclear. Therefore, it is worth using an external DC stabilized power supply with a voltage of 7 V or 9 V with a connector with an inner diameter of 2.1 mm for the display. It is compatible with the power connector on the Arduino board.

The Arduino Shields displays and keyboards give you great options and make it easy to implement even the most complex projects. Bring to life any project you have dreamed of! If you have any questions, don't hesitate to write us. We will be happy to help you choose the best Arduino Shield, and make sure it will meet all your needs and expectations!
