• PWM(Pulse Width Modulation)
Ｄ = τ/ T
D : duty cycle
τ: pulse
T ： transition
Multi Sensory Communication
ex: 0.25(D) = 1(τ)/4(T)

45. Basic Knowledge
• Voltage
– The difference in electric potential between two
points.
– Unit symbol V(Volt)
• Electric current
– A flow of electric charge through a medium.
– Unit symbol A(Ampere)
• Resistance
– The opposition to the passage of an electric current.
– Unit symbol Ω(Ohm)

50. Control using servo library
Methods see… http://www.arduino.cc/en/Reference/Servo
– attach(pin/number)
• Attach the Servo variable to a pin
– write(angle/degrees 0 - 180)
– writeMicroseconds(time/micro seconds1250 - 1750)
– read(pin/number)
• The angle of the servo, from 0 to 180 degrees.
– attached()
• Use as ServoObject.attached() returns true/false
– detach()
• Use as ServoObject.detach() detach pin from servo

#include <Servo.h> //a maximum of eight servo objects can be created
Servo myservo; // create servo object to control a servo
int pos = 0; // variable to store the servo position
void setup()
{
myservo.attach(9); // attaches the servo on pin 9 to the servo object
}
void loop()
{
for(pos = 0; pos < 180; pos += 1) // goes from 0 degrees to 180 degrees
{ // in steps of 1 degree
myservo.write(pos); // tell servo to go to position in variable 'pos'
delay(15); // waits 15ms for the servo to reach the position
}
for(pos = 180; pos>=1; pos-=1) // goes from 180 degrees to 0 degrees
{
myservo.write(pos); // tell servo to go to position in variable 'pos'
delay(15); // waits 15ms for the servo to reach the position
