Robotics (OLED)

a type of screen technology that uses organic compounds to emit light when electricity is applied

Organic Light Emitting Diode (OLED)

Unlike traditional LCDs, OLEDs don’t need a ____ —each pixel lights up independently, which leads to stunning visuals and ultra-thin designs

Backlight

Two terminals of OLED:

1. Cathode

2. Anode

How many layers does OLED have?

7 layers

OLED makes use of what to light up?

Organic Compound (Carbon)

What kind of pixels does OLED have?

Self-emissive pixels

Advantages of OLED:

1. True Black

2. Vivid Colors

3. Fast Response Time

4. Wider Viewing Angles

5. Thinner and Lighter

Disadvantages of OLED:

1. Burn-in

2. Expensive

3. Shorter Lifespan

an optoelectronic phenomenon where electrical energy is directly converted into light

this happens inside a thin layer of organic compounds sandwiched between two electrodes

Electroluminescence

Layers of OLED:

1. Anode

2. Substrate

3. Hole Injection Layer

4. Hole Transport Layer

5. Emissive Layer

6. Electron Transport Layer

7. Cathode

Acts as the base—usually glass or flexible plastic —to support the entire OLED stack.

Substrate

Transparent layer (often indium tin oxide) that removes electrons, creating "holes."

ANODE

Moves the holes from the anode layer toward the emissivelayer

Hole Injection Layer and Hole Transport Layer

Where electrons and holes recombine to emit photons—this is the lightproducing zone

Emissive Layer

Carries electrons from the cathode to the emissive layer

Electron Transport Layer

Injects electrons into the device when voltage is applied

Cathode

Are a popular choice for use with Arduino microcontrollers due to their compact size, high contrast, and low power consumption

OLED

They are commonly used to display text, graphics, and even small images in various Arduino projects

OLED

What driver chip does OLED use?

SSD1306 driver chip

SSD 1306 is compatible with the following communications:

1. I²C (Inter-Integrated Circuit)

2. SPI (Serial Peripheral Interface)

a single-chip CMOS OLED driver with controller for organic/polymer light emitting diode dot-matrix graphic display system

SSD1306 CONTROLLER

SSD1306 CONTROLLER operates at what supply?

3.3V to 5V

How much Graphic Display Data Dram (GDDRAM) does SSD1306 CONTROLLER include?

1KB

1KB area is divided into:

1. 8 pages/rows (0-7)

2. Each page has 128 columns and 64 Rows

OLED display uses I2C communication protocol, so wiring is very simple

Syntax to be used:

primarily used as the logical NOT operator within conditional statement

EXAMPLE: if (!(condition))

if (!JHENORPILLA(MALE))

{

Serial.println (“JHENORPILLA IS FEMALE”));

}

INVERT BOOLEAN (TRUE / FALSE)

is commonly used to define constants, making it easy to change values in one place and have those changes reflected throughout the code

EXAMPLE: #define Pi 3.1416

SYNTAX #define

use to place the text in specific location

column comes first before the row

setCursor (0,1)

SYNTAX setCursor

Step 1: Attach the OLED Library

TO ATTACH A LIBRARY IN ARDUINO IDE

Step 2: Define the width, height, address and other important details of the OLED
