As we are implementing software SPI, we have flexible pin options. GND should be connected to the ground of Arduino Wiring Nokia 5110 LCD display module to Arduino Unoīefore we get to uploading code and sending data to the display, let’s hook the display up to the Arduino.Ĭonnections are fairly simple. To control its brightness, you can add a potentiometer or connect this pin to any PWM-capable Arduino pin. VCC pin supplies power for the LCD which we connect to the 3.3V volts pin on the Arduino.īL(Backlight) pin controls the backlight of the display.

It’s an active low pin as well.ĭ/C(Data/Command) pin tells the display whether the data it’s receiving is a command or displayable data.ĭIN is a serial data pin for SPI interface.ĬLK is a serial clock pin for SPI interface.

You can also connect this pin to the Arduino reset so that it will reset the screen automatically.ĬE(Chip Enable) pin is used to select one of many connected devices sharing same SPI bus. It’s an active low pin meaning you can reset the display by pulling it low. Just replace the LEDs with desired color LEDs. When the screen comes off, you will notice the four LEDs soldered around the edges of the display. If you want to change the backlight of the LCD, just remove the LCD off the board by pushing the metal clips at the back side. The backlight is nothing but four LEDs spaced around the edges of the display. The LCD also comes with a backlight in different colors viz. So, for any 5V logic microcontroller like Arduino, some sort of logic level shifting is required (otherwise display may get damaged). In a normal state, the LCD consumes as low as 6 to 7mA only.Īs per datasheet, this chip operates in the range of 2.7 to 3.3 V and has 3v communication levels. Thanks to the PCD8544 controller’s versatility, it includes on-chip generation of LCD supply and bias voltages which results in low power consumption making it suitable for power sensitive applications. It interfaces to microcontrollers through a serial bus interface similar to SPI. The chip is designed to drive a graphic display of 84×48 pixels.

PCD8544 LCD DriverĪt the heart of the module is a powerful single-chip low power CMOS LCD driver controller from Philips – PCD8544. Soon they became popular among hobbyists as these displays are small(only about 1.5″), inexpensive, easy to use, fairly low power and can display text as well as bitmaps.

Remember the pre-iPhone days when cell phones had buttons and you only touched that tiny black and white screen if you needed to clean it? Nokia used these little LCDs in their 33 cell phones.Īs technology changed, these displays finally found their new place in the world of DIY.
