GND

negatively-charged pin

3.3V and 5V pin

positively charged pins

1-10+ (digital pins)

input/output

push button

is a mechanical device

used to control an electrical circuit in

which the operator manually presses a

button to actuate an internal switching

mechanism.

digitalRead

checks

the voltage level on a digital

input or the readings. To know

what pin to check

button Status

variable used to store the state of the

pushbutton. It is declared as an

integer and initialized to 0.

int led = 2;
int button = 3;
int buttonStatus ;

If Statement

compares two things and it

determines whether the comparison is true or false.

When comparing two things in programming, you use two equal signs

==

Else Statement

happens if the original condition is not met

piezo

is an electronic device that produces a voltage that when a

vibration or a mechanical strain is applied, it will be physically deformed.

When a voltage is applied to a _____, it vibrates and produces a sound.

_____________ may be used to detect as well as play tones.

piezoelectric disc

thin metal plate that

vibrates which creates a buzzing

sound

lead type and pin type
