1. These are boring
2. They were designed to be used
without knowing how a computer
works

So how do you learn computer
science concepts?
1. Learn how a computer stores and
processes information
2. Learn how to program a computer to
do various things

Computers Students
You can use Arduino to …
1. Demonstrate how a computer stores
and processes information
2. Teach how to program a computer to
do various things

Computer Concepts
Explaining the basic things a computer can do:
1) Storing Information
2) Arithmetic Operations
3) Logical Operations
4) Bitwise Operations
5) Transfer of Control
6) Repeating Actions
Teaching students to program a computer to do those things.

Storing Information
A computer stores information as a series of 0s and 1s.
000 = 0
001 = 1
010 = 2
011 = 3
100 = 4
101 = 5
110 = 6
111 = 7
Binary numbers
Decimal numbers
Memory location

Writing a Program for Storing Information
Boxes where information is stored are called memory locations.
010 = 2
Memory location
You can give it a name
x

Writing a Program for Storing Information
010 = 2
Memory location
x
int x = 2;

Writing a Program for Storing Information in Kannada
010 = 2
Memory location
ಕ
ತನುಂಬುಂಕ ಕ = ೨;

A Program to Read Information
010 = 2
Memory location
You have given the location a name
ಕ
Serial.print(ಕ);
Use that name to display the stored information

A Program to Read Information in Kannada
010 = 2
Memory location
You have given the location a name
ಕ
ಅನ್ನಕರಮ.ಛಾಪಿಸನ(ಕ);
Use that name to display the stored information

Arithmetic Operations
A computer manipulates information stored as 0s and 1s.
000 = 0
001 = 1
010 = 2
011 = 3
100 = 4
101 = 5
110 = 6
111 = 7
Memory location ಕ
Memory location ಕಿ
Operations
Addition, Subtraction, Multiplication, Division, Remainder

Writing a Program for Adding Two Numbers
010 = 2
101 = 5
Memory location x
x + y
Memory location y

Adding Two Numbers (names in Kannada)
010 = 2
101 = 5
Memory location ಕ
ಕ + ಕಿ

Subtracting Two Numbers
010 = 2
101 = 5
Memory location ಕ
ಕ - ಕಿ

Multiplying Two Numbers
010 = 2
101 = 5
Memory location ಕ
ಕ * ಕಿ

Dividing Two Numbers
010 = 2
101 = 5
Memory location ಕ
ಕ / ಕಿ

Remainder from Dividing Two Numbers
010 = 2
101 = 5
Memory location ಕ
ಕ % ಕಿ

Bitwise Operations
000 = 0
001 = 1
010 = 2
011 = 3
100 = 4
101 = 5
110 = 6
111 = 7
Memory location ಕ
Operations
XOR, Shifting

XOR of Two Numbers
010 = 2
101 = 5
Memory location ಕ
ಕ ^ ಕಿ

Shifting a Number
010 = 2
Memory location ಕ
ಕ >> 1

Logical Operations
000 = 0
001 = 1
010 = 2
011 = 3
100 = 4
101 = 5
110 = 6
111 = 7
Memory location ಕ
Operations
Equal, Not Equal, Greater, Lesser, And, Or, Not

Two Numbers Being Equal
010 = 2
101 = 5
Memory location ಕ
ಕ == ಕಿ

Two Numbers Being Unequal
010 = 2
101 = 5
Memory location ಕ
ಕ != ಕಿ

One Number Being Less Than Another
010 = 2
101 = 5
Memory location ಕ
ಕ < ಕಿ

One Number Being Less Than or Equal to Another
010 = 2
101 = 5
Memory location ಕ
ಕ <= ಕಿ

One Number Being Greater Than Another
010 = 2
101 = 5
Memory location ಕ
ಕ > ಕಿ

One Number Being Greater Than or Equal to Another
010 = 2
101 = 5
Memory location ಕ
ಕ >= ಕಿ

And
010 = 2
101 = 5
011 = 3

Transfer of Control
A computer manipulates information stored as 0s and 1s using
instructions stored as 0s and 1s.

instructions stored as 0s and 1s.
000 = 0 int a = 1 000 = assign
001 = 1 int b = 2 000 = assign
010 = 2 a = a + b 010 = +
011 = 3 b = a - b 011 = -
100 = 4 a = a - b 100 = -
101 = 5 (a > b) 100 = >
110 = 6 if (a > b) 111 = jump
111 = 7 print a 001 = print

Memory location a
if ( a < b )
Memory location b

If (ಆದರ in Kannada)

101 = 5
Memory location ಕ
ಆದರ ( ಕ < ಕಿ )

Repeating Actions
You can repeat actions by jumping backwards.
000 = 0 int i = 0 000 = assign
001 = 1 (i >= 10) 100 = >
010 = 2 if (i >= 10) 111 = jump
011 = 3 sum + a 010 = +
100 = 4 sum = sum+a 000 = assign
101 = 5 (i < 10) 100 = >
110 = 6 if (i < 10) 111 = jump
111 = 7 print sum 001 = print
Memory Instructions

For
000 = 0
000 = 0
Memory location sum
int sum = 0, i = 0;
for (; i<10; ++i) {
sum = sum + i; }
Memory location i

000 = 0
Memory location ಒುಂಟಿಗ
ತನುಂಬುಂಕ ಒಟಿಿಗ =0,ಐ=0;
ಕರಮವಾಗಿ (;ಐ<೧೦;++ಐ){
ಒಟಿಿಗ = ಒಟಿಿಗ +ಐ; }
Memory location ಐ

While

101 = 5
000 = 0
Memory location a
int sum = 0;
while (sum+a < b) {
sum = sum + a; }
Memory location b
Memory location sum

While (ಆಗನವಾಗ in Kannada)
