The contents of this Course :
This course is a workshop ( no much of Theories ) , so will involve in :
1. Identify the ARDUINO board parts and their works / power suppling methods / output and input pins .
2. Identify the Basic programming functions ( reading inputs and returning Outputs )
3. Identify the signals types that the ARDUINO treat with
4. Using sensors : a. measuring the room temp
b. measuring the light intensity
c. detection the movement .
d. Making a distance measuring tool ( using ultrasonic sensor )
e . --- working on a new sensor individuality ---

6. Using motors : a . DC motor
b. servo motor
c. stepper motor
5. Identify the H-BRIDGE and its usage
7. Using the KeyPad
8. Identify Serial interface
9. Using LCD display.
10 . -- Task : making a personal messenger --
11. Using a inferred IR sensor with remote Control
12 . use a seven segment screen
*** if there enough time , we will Do a PID
Control by ARDUINO ☺

Arduino : is a MICROCONTROLLER , able to be programmed by the users via ( Arduino c programming) .
( in fact , it is a Tiny computer )
MICROCONTROLLER : integrated circuit (fig 1.1) , contain CPU , memory ( RAM, ROM, Flash) ,
inputs & outputs ports

Digital Signal : Is a signal consists from tow values ( 0 or 1 )
To read a digital signal use the function : digitalRead();
To write a digital signal use the function : digitalWrite ();
In Arduino :
(logic 0) = ( volts 0) = LOW = OFF
( logic 1) = (volts 5) = HIGH = ON
Digital signals received and send by using the 14 pins

1 give a name for the pin “Optional”

2 Open the pin mode as ( INPUT / OUTPUT)

3 The pin is ready to Use by its name or
By its number

Analog Signal : Is a sinusoidal signal
To read an Analog signal use the function : analoglRead();
To write a digital signal use the function : analogWrite ();
Analog signals received by using the (A0 …. A5) pins
Analog signals sent by using the (~3 , ~5, ~6, ~9 ,~10, ~11) pins
Arduino treat with this type of signals as a ( 8 bit digital data )
(0 – 5 volt)  (0 – 255)

While the code is running , try to open :
Tools  Serial Plotter

Map  is a function defined in Arduino C language .
we use it to Re-maps a number from one range to another .
General form:
New_range = map (val , from min , from max , to min , to max);
In pervious example:
New_val = map(val, 0 , 1023 , 0 , 255) ;
// its convert val from (0-1023) range to (0-512)

3
Tow Thing you have start with:
1. Get the data sheet
2. find the range of measuring.
3. Use the map() function.
Example:
I have to measure the temperature in my room.
The sensor needed is TMP36 sensor. How can I start with ?!
1. Search in google for [TMP36 sensor].
2. Find the voltage range.
3. Find the measuring range.
4. Try to know how dose the sensor work.

3
In the pervious (ATMP36 )sensor .
if I need to eliminate the measured temperature values.
Measure from (0C to 100C for example )
Google it and teach yourself ☺

DC Motors
* Arduino Run Dc motors and controlling its speed by PWM , By code
analogWrite(pin,255);
* Arduino can Supply 5volt up to 400mA ,
to run 12volt Dc motors we need H-bridge
Dc Motor for Arduino Car Kite
“ 5 volt “
General Purpose Motor
“ 5 volt ”
High Power Dc motor
“ 12 volt ”

Servo Motors
* Motor rotates with certain angles in [Degrees], i.e: 60 , 90 , 180 …
* <Servo.h> Library used to drive the Servo Motor

#include <Servo.h>
Servo myservo; // create myservo
object to control a servo
myservo.attach(9); // attaches
the servo on pin 9 to the servo
object
myservo.write(pos); // tell servo to go
to position in variable 'pos'
