Step 1: The Controller

Arduino Motor Shield (L298N)

=================================================================================
Introduction
=================================================================================
This motor shield allows Arduino to drive two channel DC motors. It uses a L298N chip which deliveries output current up to 2A each channel. The speed control is achieved through conventional PWM which can be obtained from Arduino’s PWM output Pin 5 and 6. The enable/disable function of the motor control is signalled by Arduino Digital Pin 4 and 7.

The Motor shield can be powered directly from Arduino or from external power source. It is strongly encouraged to use external power supply to power the motor shield.

//PWM Speed Control

//Arduino PWM Speed Control
int E1 = 6;
int M1 = 7;
int E2 = 5;
int M2 = 4;

void setup()
{
pinMode(M1, OUTPUT);
pinMode(M2, OUTPUT);
}

void loop()
{
int value;
for(value = 0 ; value <= 255; value+=5)
{
digitalWrite(M1,HIGH);
digitalWrite(M2, HIGH);
analogWrite(E1, value);   //PWM Speed Control
analogWrite(E2, value);   //PWM Speed Control
delay(30);
}
}

=======================================

//PLL Speed Control

//Arduino PLL Speed Control
int E1 = 7;
int M1 = 6;
int E2 = 4;
int M2 = 5;

void setup()
{
pinMode(M1, OUTPUT);
pinMode(M2, OUTPUT);
}

void loop()
{
int value;
for(value = 0 ; value <= 255; value+=5)
{
digitalWrite(M1,HIGH);
digitalWrite(M2, HIGH);
analogWrite(E1, value);   //PLL Speed Control
analogWrite(E2, value);   //PLL Speed Control
delay(30);
}
}

I use for Fan

The Code :

void kipas()
{
digitalWrite(kipasPin1, HIGH);
digitalWrite(kipasPin2, LOW);
digitalWrite(enablePin,HIGH);
delay(1000);
}

void kipas_mati()
{
digitalWrite(kipasPin1, LOW);
digitalWrite(kipasPin2, HIGH);
digitalWrite(enablePin,LOW);
delay(1000);
}

Schematic Arduino Touch Wardrobe

====================================================================================
Touch Switch
====================================================================================

There are a number of different types of TOUCH PLATES and different effects
can be created by the circuit.

1. Touch a set of pads and the project turns on.
When the finger is removed, the circuit turns off.
The finger can touch the pads for any length of time.
We also include the feature where the circuit extends the ON period,
so the circuit stays on for a length of time after the finger is removed.
This is shown in Circuits A.
