Electronics & Robotics Glossary
Master the language of electronics and robotics. Search for terms or browse by category.
? Basic Electrical Concepts
Voltage (V): The electrical potential difference between two points. Measured in volts. Think of it as electrical "pressure" that pushes current through a circuit.
Current (I): The flow of electrical charge through a conductor. Measured in amperes (amps). Like water flowing through a pipe.
Resistance (R): Opposition to current flow. Measured in ohms (O). Like friction in a water pipe that slows down flow.
Ohm's Law: V = I � R. The fundamental relationship between voltage, current, and resistance in electrical circuits.
Power (P): The rate of energy consumption. Measured in watts (W). Calculated as P = V � I.
?? Electronic Components
LED (Light Emitting Diode): A semiconductor device that emits light when current flows through it. Only allows current to flow in one direction.
Resistor: A component that limits current flow. Used to protect other components and control voltage levels.
Capacitor: Stores electrical energy temporarily. Used for filtering, timing, and power supply smoothing.
Transistor: A semiconductor switch that can amplify signals or act as a digital switch. The building block of all digital electronics.
Diode: Allows current to flow in only one direction. Used for protection and rectification.
?? Robotics & Control
Microcontroller: A small computer on a single chip that can be programmed to control electronic devices. The Arduino UNO uses an ATmega328P microcontroller.
Sensor: A device that detects and responds to physical input from the environment (light, temperature, motion, etc.).
Actuator: A device that converts electrical signals into physical motion (motors, servos, solenoids).
PWM (Pulse Width Modulation): A technique for controlling power by rapidly switching it on and off. Used to control motor speed and LED brightness.
I2C (Inter-Integrated Circuit): A communication protocol that allows multiple devices to communicate using just two wires.
?? Programming Concepts
Digital Signal: A signal that can only be HIGH (5V) or LOW (0V). Used for on/off control and digital communication.
Analog Signal: A continuous signal that can have any value within a range. Used for sensors that measure varying quantities.
Loop: A programming structure that repeats a set of instructions. The main loop() function in Arduino runs continuously.
Variable: A named storage location in memory that holds a value that can change during program execution.
Function: A reusable block of code that performs a specific task. Can accept inputs (parameters) and return outputs.
About This Learning Platform
