Introduction: Earthquake Detector
This is a Earthquake Detector where i have added a led useing tx and 3.3volt. The led is hidden under the blue wire. Here's how i connected the circuit. 3.3volt to + of the board then digital tx1 to - ground of the board then plug in your LED with the cathode being + and anode being - A0 to + and ground to - of board run a jumper from ground to the 220-ohm resistor and then run a jumper from the + to the 220-ohm resistor and put a rectifier diode in front of the resistor like the picture shows run 2 more jumpers inline with the resistor and the diode and hook your piezo speaker up with the red wire being + and the blue being - in the ardino program use the serial monitor to see the detector work tap the piezo and you will see this #. Here is the code start here---------------------> /*
Earthquake Detector
Sensing the tremors on a surface
Fritzing.org
This script will sense the tremors on a surface and output it in the serial monitor.

float tremor; // stores the analog value
int sensorPin = 0; // pin where the sensor is connected to
void setup()
{
Serial.begin(115200); // initialisation of the serial connection
}
void loop()
{
tremor = analogRead(sensorPin); // reading analog sensor value
if (tremor>0){ // if tremor is sensed
for (int i=0; i
}
Serial.println("");
}
delay(0); // just wait a little

what are the things we need
5 years ago on Introduction
can you explain earthquake detector with accelerometer MMA 7361
7 years ago on Introduction
Can you explain step by step how where and why you put the the components on the breadboard.
Can you explain the code more/
how do you detect earthquakes with this device.
This is brilliant but i want to replicate this if you can help.
Thanks smart guy.
