Nokia 5110 LCD Arduino: Retro Display Revival for Modern Projects

Some components refuse to die, and for good reason. The Nokia 5110 LCD—originally designed for a mobile phone that dominated the late 1990s—has found a second life in the maker community. After years of designing embedded systems, I still grab the Nokia 5110 LCD Arduino combination for projects where I need a graphics-capable display that won’t drain batteries or blow the budget.

This 84×48 pixel monochrome screen runs on a PCD8544 controller and costs less than a decent coffee. Yet it delivers crisp text, custom graphics, and even simple animations visible in direct sunlight. In this tutorial, I’ll walk you through connecting this retro display to your Arduino, explore the best libraries, and share practical code examples that you can use immediately.

Why the Nokia 5110 LCD Still Matters

You might wonder why anyone would use a display from a 25-year-old phone when OLEDs and color TFTs exist. The answer comes down to practical engineering trade-offs.

Advantages Over Modern Alternatives

The Nokia 5110 LCD excels in several areas that matter for real-world deployments. First, power consumption is remarkably low—around 6-7mA with the backlight off. Battery-powered projects can run for weeks on a single charge. Second, the display remains perfectly readable in bright sunlight, unlike OLEDs that wash out outdoors. Third, the price point is unbeatable: bulk purchases bring the cost under $2 per unit.

I’ve deployed these screens in outdoor weather stations, bicycle computers, and industrial monitoring equipment. They just work, year after year, without drama.

Hardware Requirements

Before connecting anything, gather your components and understand the voltage requirements—this trips up many beginners.

Components Needed

Arduino Uno/Nano/Mega	1	Any 5V Arduino works
Resistors (10kΩ)	4-5	For voltage level shifting
Resistors (1kΩ)	4-5	Alternative divider values
Jumper Wires	8	Male-to-female preferred
Breadboard	1	For prototyping

The Voltage Level Challenge

Here’s where people run into trouble. The Nokia 5110 LCD runs on 3.3V logic, but most Arduino boards output 5V on their digital pins. Connecting 5V signals directly to the display can damage the PCD8544 controller—sometimes immediately, sometimes after a few hours of operation.

You have three options for level shifting:

Resistor voltage dividers: Simple and cheap. A 10kΩ and 4.7kΩ resistor pair brings 5V down to approximately 3.2V. This works reliably for the relatively slow SPI speeds we’re using.

Logic level converter modules: Cleaner solution that handles bidirectional communication. Overkill for this display since we only send data, never receive.

Use a 3.3V Arduino: Pro Mini 3.3V or ESP8266/ESP32 boards eliminate the issue entirely. Direct connection, no resistors needed.

Wiring Nokia 5110 LCD to Arduino

The display module typically has 8 pins. Some boards label them differently, so match by function rather than name.

Connection Table with Level Shifting

Nokia 5110 Pin	Function	Arduino Uno Pin	Resistor Divider
RST	Reset	Pin 6	10kΩ + 4.7kΩ
CE	Chip Enable	Pin 7	10kΩ + 4.7kΩ
DC	Data/Command	Pin 5	10kΩ + 4.7kΩ
DIN	Data In (MOSI)	Pin 4	10kΩ + 4.7kΩ
CLK	Clock	Pin 3	10kΩ + 4.7kΩ
VCC	Power	3.3V	Direct connection
BL	Backlight	Pin 9 (PWM)	330Ω to ground
GND	Ground	GND	Direct connection

For the resistor dividers, connect the 10kΩ resistor between the Arduino pin and the display pin, then connect the 4.7kΩ resistor from the display pin to ground. The junction point delivers approximately 3.2V when the Arduino outputs 5V.

The backlight pin connects to a PWM-capable Arduino pin through a current-limiting resistor. This allows software brightness control and saves power when you don’t need illumination.

Software Libraries for Nokia 5110 LCD Arduino

Several libraries support the PCD8544 controller. Each has strengths depending on your project requirements.

Library Comparison

Library	Flash Usage	Features	Learning Curve
Adafruit PCD8544	Medium	Graphics primitives, fonts	Easy
U8g2	Higher	Extensive fonts, efficient	Medium
PCD8544 (Sparkfun)	Low	Basic functions	Very Easy
LCD5110_Graph	Medium	Graphics focused	Easy

For beginners, start with the Adafruit PCD8544 library paired with Adafruit GFX. The combination provides drawing functions for lines, rectangles, circles, and text with minimal code.

For projects where memory is tight, U8g2 offers a page buffer mode that reduces RAM usage significantly—critical on ATmega328-based Arduinos with only 2KB of RAM.

Installing Libraries

1. Open Arduino IDE
2. Navigate to Sketch → Include Library → Manage Libraries
3. Search “Adafruit PCD8544” and install
4. Also install “Adafruit GFX Library” (dependency)
5. Restart Arduino IDE

Code Examples

  display.display();

}

Practical Project Ideas

The Nokia 5110 LCD Arduino pairing works well for numerous applications.

Portable Multimeter Display: Combined with voltage and current sensing ICs, build a compact measurement tool that runs for days on batteries.

Bicycle Computer: Track speed, distance, and trip time. The sunlight readability makes it perfect for outdoor use.

Mini Game Console: The 84×48 resolution supports simple games like Snake, Pong, or Breakout. Add a few buttons and you have a complete handheld.

Server Room Monitor: Display network statistics, CPU temperatures, or alert statuses at a glance.

Troubleshooting Common Issues

Problem	Likely Cause	Solution
Blank screen	Contrast too low/high	Adjust setContrast() value (try 40-60)
Garbled display	Incorrect wiring	Verify pin connections, especially DC and CE
Faint display	Missing level shifters	Add resistor dividers on signal lines
Partial display	Damaged controller	Replace module (they’re cheap)
Display works then fails	5V damage over time	Add proper level shifting

The contrast setting varies between individual displays. I typically start at 50 and adjust up or down until text appears crisp without dark bleeding.

Frequently Asked Questions

Can I use Nokia 5110 LCD with ESP8266 or ESP32?

Yes, and it’s actually easier since both boards use 3.3V logic. Connect the display directly without voltage dividers. Just adjust the pin definitions in your code to match the GPIO numbers on your ESP board.

Why does my display show random pixels or lines?

This usually indicates a wiring problem or timing issue. Double-check your connections, especially the DC (Data/Command) pin. Also try reducing the SPI speed in your library settings if available.

How do I display images on the Nokia 5110?

Convert your image to a monochrome bitmap (84×48 pixels or smaller), then use online tools like image2cpp to generate a byte array. The Adafruit GFX library’s drawBitmap() function displays the array on screen.

Is the Nokia 5110 LCD better than OLED for battery projects?

For battery life, yes. The Nokia 5110 draws 6-7mA versus 20-30mA for comparable OLEDs. However, OLEDs offer better contrast and don’t require backlight for visibility in dark conditions. Choose based on your specific requirements.

Can I run multiple Nokia 5110 displays from one Arduino?

Yes, each display needs its own CE (Chip Enable) pin, but they can share CLK, DIN, DC, and RST lines. Select which display receives data by setting its CE pin low while keeping others high.

Wrapping Up

The Nokia 5110 LCD Arduino combination proves that older technology still has legitimate applications. When you need a display that’s cheap, power-efficient, and readable in any lighting condition, this retro screen delivers without pretense.

Start with the basic examples above, experiment with contrast settings for your specific module, and build from there. Once you’ve mastered the fundamentals, you’ll find yourself reaching for this display whenever project constraints favor practicality over flashiness—which, in professional embedded development, happens more often than you’d think.
