Resistor
Does a resistor have polarity?
None
Name the three types of jumper wires.
Male-to-Male, Male-to-Female, Female-to-Female
Name the three Arduino boards discussed in class.
Uno, Nano, Mega
Which data type stores whole numbers?
int (integers)
Which component acts as the "brain" of the robot?
Arduino/Microcontroller
What is the 4th band of a resistor called?
Multiplier
Does a LED have polarity?
Yes. It has an anode (+) and cathode (-).
Which Arduino board has the most input/output pins?
Arduino Mega
Which data type stores decimal numbers?
float
Should you touch exposed wires while the Arduino is powered?
No
Read this resistor: Red - Red - Brown - Gold
220Ω ±5%
Which leg of the LED is positive?
The longer leg (Anode).
Which pins are used to detect only YES or NO (HIGH or LOW) signals?
Digital Pins
Which data type stores a single letter?
char
Can you plug a 220V AC outlet directly into an Arduino Uno?
No
Read this resistor: Brown - Black - Red - Gold
1,000Ω (1kΩ) ±5%
Are the holes in one horizontal row in a breadboard connected together?
Yes
Which pins are used to read values from a temperature sensor?
Analog pins
What data type would you use to store the value 13.75?
float
What can happen if the positive and negative terminals are connected incorrectly?
The component may not work or may be damaged.
Why do we use a resistor with an LED?
To limit the current so the LED doesn't burn out.
What are the long red and blue lines on the side of the breadboard called?
Power Rails
Which Arduino pin is connected to the negative side of a circuit?
GND (Ground)
Which data type should you use to store the value 1/2
float
What are the two main parts of a robot?
Hardware and Software
