The document discusses the concept of earthquakes and the history of earthquake detection, highlighting key inventions such as the 'dragon jar' seismoscope and the development of the seismometer. It outlines the components needed for building an earthquake detector using Arduino technology, including an LCD display and various sensors. The process includes circuit patching, coding, and assembling the device for its intended function.

3. EARTHQUAKE
 A sudden violent shaking of the ground,
typically causing great destruction, as a
result of movements within the earth's crust
or volcanic action.

4. A BRIEF HISTORY OF EARTHQUAKE DETECTION
 132 A.D. - Chinese Philosopher Chang Heng
invents ‘Dragon Jar’ seismoscope.
 1855 - Luigi Palmieri invents seismometer using
tubes of mercury and electricity, able to record
earthquake time and intensity. Carl Kreil
develops vertical Pendulum Seismograph.
 1879 - Seismographs developed in Japan by the
British group.

5. COMPONENTS:
 Arduino
 LCD Display (16*2)
 Bread boards
 Vibration sensor
 Connecting wires
 Potentiometer
 Resistor

6. CIRCUIT PATCHING
 Placed LCD and Arduino in bread board.

7. CIRCUIT PATCHING : (CONTINUED)
 Making connections between LCD display,
Arduino , and other circuit components
according to circuit diagram.

8. CIRCUIT PATCHING : (CONTINUED)
 Make code for running the required process.
 Burn the code in Arduino.
 Now circuit is ready for running the specific
task.
