Please use your OWN WORDS, not wikipedia's definition :-)

Which one of these are considered Variables? *

Float

While

Int

char

For

Required

What is the maximum value which is stored by an 8-Bit Variable? *

Hint: Bits = 2!

256

1024

4096

What Technique can be used to dim an LED or slow down current to a motor? *

Time Delay Integration (TDI)

I want to turn on an LED when an external Voltage is measured above a digital value of 100, which code will work for this? *

while( voltage > 100 ) { Turn LED on; }

for ( LED =0 ; led < 100 ; ++ LED ) { Measure Voltage input ;}

while (100 > voltage) {turn LED off ; }

if ( voltage > 100 ) { turn LED on ; }

None of the above

A Watt is a measurement of *

Current x Resistance

measure weather sensors and send measured values to a computer

How would you describe our class project, the automatic door? *

How will it work? What is needed for it to work?

Why are some LED's white, others red or blue? *

In order to complete a circuit on the Arduino, We always need an output or input line, plus: *

A sensing wire

A resistor

A measurement

A ground connection

A closed switch

If Voltage can be thought of as the number of lanes on a highway, what can be current thought of as? *

The size of the lanes on a highway

The maximum speed on the freeway

The number of cars on the freeway

The size of cars on the freeway

None of the Above
