Three Electric Products Should You Know About

A liquid crystal display is a display technology that helps to digitally display readings on a medium such as computer, television,digital watch, calculator, and so on.LCD devices could be battery operated or electricity operated and LCD screens have the capability of displaying arbitrary images in a variety of colors.There are many devices uses the LCD screen in the world today,such as mobile phones,tablets,portable computers, Nokia 5100 module and so on.

LCDs are available to display arbitrary images or fixed images which can be displayed or hidden,such as preset words, digits,and 7-segment displays as in a digital clock.They use the same basic technology,except that arbitrary images are made up of a large number of small pixels,while other displays have larger elements.

And LCDs are used in a wide range of applications including computer monitors, televisions,instrument panels,aircraft cockpit displays,and signage.They are common in consumer devices such as video players, and telephones,and have replaced cathode ray tube displays in most applications.

Other electric product is 3 color LED module.The joystick module is useful for when you need to control a variable direction.This is easier to see in a video game when you want your character to walk slowly,you only move the joystick a bit but then you want your character to run, you move the joystick all the way.Because the joystick is analog,you can determine how much you want the posision to move.This Joystick module also includes a built-in button on the joystick itself.Press the top of the stick and instant button.To use the Joystick module will depend on what you want to do with it.The module drivers can poll the XY direction or trigger a joystick/button event.

The last electric product I would like to talk about is RGB 3 color LED module.As we all know that,A light-emitting diode (LED) is a semiconductor light source.LEDs are used as indicator lamps in many devices and are increasingly used for general lighting.With this function, this module will be compatible with Arduino DIY project.And it comes with three colors: red, green and blue.
