Space

The area around, between, or inside objects.

Positive Space

The occupied area around, between, or inside objects.

Negative Space

The empty area around, between, or inside objects.

Value

The degree of lightness or darkness of a color.

Photopea

A web-based image and graphics editor used for editing pictures and creating designs.

Layers

A feature in Photopea that allows you to edit different parts of a design separately.

Arduino UNO

A popular microcontroller board used to create electronic projects and prototypes.

Microcontroller

The main chip on the Arduino board that executes the program.

Digital Pins

Pins on the Arduino UNO that read or control digital signals.

Analog Input Pins

Pins on the Arduino UNO that read varying voltage levels from sensors.

USB Port

Connects the Arduino to a computer for programming and communication.

Power Jack

Provides external power to the Arduino UNO.

Reset Button

Restarts the Arduino program.

5V Pin

Provides approximately $5\,V$ of power.

GND (Ground)

Electrical reference/return path in an electronic circuit.

setup()

Part of the Arduino program structure that runs once.

loop()

Part of the Arduino program structure that runs repeatedly.

pinMode()

An Arduino command that sets a pin as INPUT or OUTPUT.

digitalWrite()

An Arduino command that sets a digital pin HIGH or LOW.

digitalRead()

An Arduino command that reads digital input.

analogRead()

An Arduino command that reads analog input.

delay()

An Arduino command that pauses the program for a specified time.

LED

Light-Emitting Diode; produces light when current passes through it in the correct direction.

Anode (+)

The positive leg of an LED, usually the longer leg, connected toward the positive side.

Cathode (-)

The negative leg of an LED, usually the shorter leg, connected toward GND.

Current-Limiting Resistor

A component used with an LED to help prevent excessive current.

7-Segment Display

An electronic display made of seven individual LED segments (labeled a, b, c, d, e, f, g) used to display numbers and some letters.

Common Cathode (CC)

A 7-segment display configuration where cathodes are connected together and a segment generally turns ON with HIGH.

Common Anode (CA)

A 7-segment display configuration where anodes are connected together and a segment generally turns ON with LOW.
