The culprit

3. MOTIVATION
A project that showcases skills related to electricity/electronics and computer systems
Utilization of the Arduino as a microcontroller
Creating a device to help pet owner train a cat not to scratch on furniture
The motivation for this project

4. INTRODUCTION Piezo based touch sensor alarm circuit Simple Effective
Inexpensive
Arduino microcontroller module
Support readily available
Easy to use
Senses when Jinx scratches the couch
Cat touches piezo sensor-triggers an alarm for 2.5 seconds
Arduino sounds and alarm and scares him away
Jinx is scared away or I can come and shew him away
Piezo sensor-Arduino microcontroller anti-cat scratching prototype

5. PROBLEM STATEMENT Train my cat not to destroy my couch
Prolong life of the couch
Prevent possible injury to the cat
Make an easily attainable feline training apparatus
Constraints
The sensor will only activate if enough pressure is applied
What if the cat scratches a section that is not covered by the sensor mat?
Will the cat be scared by the alarm?

6. ASSUMPTIONS Basic knowledge of electrical circuits
An Arduino microcontroller
Basic knowledge of Arduino program code
The device will not harm the cat
The device will not frighten the cat

7. PROPOSED SOLUTION Flow Chart No Yes Yes START
Construct the alarm circuit
Brainstorm and search for informative resources
Does it work?
Troubleshoot and fix No
Does the code work?
Choose an alarm circuit diagram as a basis for project
Yes
Combine alarm and Arduino
Yes
Construct a parts list
Begin Arduino setup and coding
Test and troubleshoot if necessary
Order circuit parts , an Arduino, and GSM shield
Time ran out-downscale occurred
Working version complete

8. ARDUINO KIT

9. PLAN FOR SENSOR MAT

10. ARDUINO PROGRAM CODE #define sense A0 #define buzzpin 9 void setup() {
void setup() {
  // put your setup code here, to run once:
  pinMode(sense, INPUT);
  pinMode(buzzpin, OUTPUT);
  Serial.begin(9600); }
void loop() {
  // put your main code here, to run repeatedly:
  int val = analogRead(sense);
  Serial.println(val);
  if (val >= 1005){
      buzz();
  }
  //when piezo switch is pressed, start buzzing
void buzz () {
  digitalWrite(buzzpin, HIGH);
  delay(2500);
  digitalWrite(buzzpin, LOW);
  //while beep for 2.5 sec after piezo is pulled low (switch released)

11. COMPLETED PROJECT SCALED DOWN VERSION

12. RESULTS A piezo sensor alarm circuit Working Arduino
Functional Arduino program code
Working piezo buzzer alarm device

13. CONCLUSIONS Learning experience Learned about Arduino program code
Learned about piezo sensors
Expanded my knowledge of electrical circuits
Learned about project management
Learned the importance of being able to ask for help and working as a team

14. FUTURE IMPROVEMENTS Construct a couch mat with piezo sensors
Add a GSM shield to enable text message and capabilities
Write program code for text, , and video streaming
Build an aesthetically pleasing case for the project
Incorporate a camera system for surveillance to stream to a smart phone
