Where

is

the power

supply?To power up the teensy just connect it to your laptop

using USB port

Very

important

:

DOUBLE CHECK your circuit before connecting the teensy

to your laptop. Invalid connection may damage the

microcontroller or your USB port.

What

is

a

microcontroller?

Small computer Able

to do

tasks

like

turn

on

/

off

a LED,

rotate

a motor,

read

values

from

different

sensors

, etc…

It’s

the

brain

Slide37

What

is

a

microcontroller?

Digital Pins

The

teensy

2.0

has

11 digital pins,

and

they

can

be

used

to

send

or

read

signals

They

only

have

2

states

:

1 (

High

state

)

0 (

Low

state

)

Like

the

push

button

,

when

it’s

activated

the

current

will

flow

from

the

pin to

the

component

that

is

connected

to

it

Arduino

Code

The

code is always written and

read

from

the

top to

bottom

,

and

left

to

right

A

command

as

always

to

end

with

a “ ; ”

except

when

it’s

a

function

or

a

condiction

It’s

good

practice

to

comment

our

code

, to do

that

just

type

“ // ”

and

the

rest

of

the

text

after

is

just

comments

Variables are used to store information to be used in a computer program

They also provide a way of labeling data with a descriptive name

 Variables are containers that hold information

Challenge

nº 4

Send

a S.O.S.

signal

from arduino with the built-in LED

You

have

15 minutes!!

Slide70

Using

teensy

to

read a signal

Now you learn how

to use

the

teensy

to

read

a

signal

To do

that

,

we

will

be

using

a

push

botton

to

send

the

signal

to

the

teensy

Depending

on

the

state

off

the

pin

that

we

will

read

,

the

LED

should

be

on

or

off

Slide71

Using

teensy

Use

the

PIN 0 of teensy to read a signal

Function to configures the

specified pin to behave either

as an input or an output

Number

of

the

pin

Direction

of

the

signal

0

INPUT

Function

that

returns

the

state

of

the

pin

PIN to

read

Slide72

Using

teensy

If

condition is used to compare values and take

action

according

to

the

result

Our

condition

True

False

= to

assign

values

== to compare

values
