So Now, we know that each character has (5*8=40) 40 Pixels and for 32 Characters we will have (32*40) 1280 Pixels. A Single character with all its Pixels enabled is shown in the below picture. Because our LCD is a 16*2 Dot matrix LCD and so it will have (16*2=32) 32 characters in total and each character will be made of 5*8 Pixel Dots. These black circles consist of an interface IC and its associated components to help us use this LCD with the MCU. Okay, what is this two black circle like things on the back of our LCD? It is okay if you do not understand the function of all the pins, I will be explaining in detail below. Normal LED like operation to illuminate the LCD connected with GND. Normal LED like operation to illuminate the LCD Pins used to send Command or data to the LCD. Must be held high to perform Read/Write Operation Toggles the LCD between Read/Write Operation Below is the Pinout and Pin Description of 16x2 LCD Module:Ĭonnected to the ground of the MCU/ Power sourceĬonnected to the supply pin of Power sourceĬonnected to a variable POT that can source 0-5VĬonnected to a MCU pin and gets either 0 or 1. But the most used one is the 16*2 LCD, hence we are using it here.Īll the above mentioned LCD display will have 16 Pins and the programming approach is also the same and hence the choice is left to you. There are a lot of combinations available like, 8×1, 8×2, 10×2, 16×1, etc. 16×2 LCD is named so because it has 16 Columns and 2 Rows. ![]()
