20x4 Graphical LCD 2004A

\n\nThe majority of embedded projects use LCD modules because they are readily available, inexpensive, and programmer-friendly. In our daily lives, the majority of us would have encountered these displays, either at PCOs or calculators. 20x4 Blue/Green Colored Liquid Crystal Display, Alphanumeric 20x4 graphical lcd 2004a It can show four lines of text, each with a maximum of 20 characters, which is more than the 16x2 LCD display but has nearly identical programming. These symbols could be text, numbers, graphical representations, or even unique characters. It can be used for DIY projects, IoT project data displays, etc.\n\n\n\nWe understand that each character has a size of 40 pixels, making a total of 3200 pixels for 80 characters. Additionally, instructions regarding the position of the pixels should be given to the LCD. Since it is a demanding task for the microcontroller, a driver IC like the ST7066, mounted on the back of the LCD module, is used. Data from the microcontroller is processed and displayed on the LCD screen by the device. If you only need to connect a few lines to the microcontroller, you can use it in 4 bit or 8 bit parallel interface mode.\n\n
