Arduino Basics
What is the main programming language used for Arduino?
C/C++
This type of code package lets you control hardware like servos, LEDs, or sensors without writing every line yourself
Library
The opposition to the flow of electric current in a material, measured in ohms (Ω)
Resistance
What is the main purpose of a breadboard?
To prototype circuits
This inexpensive sensor (HC-SR04) is commonly used to measure distance in robotics
Ultrasonic Sensor
What board function uploads code to an Arduino?
Upload (cmon now)
The unit named for Georg Simon that measures resistance.
Ohm
This device is used to measure voltage, current, and resistance.
Multimeter
What are the horizontal rows on a breadboard used for?
Connecting components
These sensors help a robot follow a path on the ground.
Infrared Sensors / Line-following
What pin type on an Arduino is used for digital input/output?
Digital Pins
Component that stores charge on two plates separated by a dielectric.
Capacitor
What component is used in series with an LED or any other loads to prevent burnout?
Resistor
What separates the two sides of a breadboard's terminal strips?
Central Ditch
This microcontroller board, often paired with Arduino in robotics, is designed to drive two DC motors with ease
Motor Driver / L298N
What Arduino function reads the state of a digital pin?
digitalRead()
What is the maximum rotation angle of a standard servo?
180 degrees
How do you calculate current in a circuit?
I = V/R
current = voltage/resistance
How are power rails typically labeled on a breadboard?
+ and -
A popular, low-cost microcontroller with integrated Wi-Fi and Bluetooth capabilities
ESP32
What does the delay() function do in Arduino code?
Pauses execution
Four diodes arranged this way convert AC to pulsating DC.
4 Bridge Rectifier
What law relates current, voltage, and resistance in an LED circuit?
Ohm’s Law
What is the maximum current a breadboard terminal can handle?
Variable, ~200mA
A robot arm needs this type of coordinate system (named for a French mathematician) to calculate positions in 2D or 3D space.
Cartesian Coordinate System
