Adafruit_ILI9341 library:
Adafruit_MPU6050 library:
Wire library:


The purpose of this sketch is to display the acceleration of x, y and z axis
on a TFT display and use a buzzer to sound an alarm if a vibration was detected.

Connections from the Arduino to the breadboard:

• Arduino GND pin → Breadboard ground line

• Arduino 5V pin → Breadboard 5V line


Connections from the MPU-6050:

• MPU-6050 VCC pin → Breadboard 5V line

• MPU-6050 GND pin → Breadboard ground line

• MPU-6050 SDA pin → Arduino pin A4

• MPU-6050 SCL pin → Arduino pin A5


Connections from the passive buzzer:

• passive buzzer GND pin → Breadboard ground line

• passive buzzer VCC pin (+ pin) → Arduino pin 3


Connections from the TFT Display to the breadboard:

• TFT Display VCC pin → Breadboard 5V line

• TFT Display GND pin → Breadboard ground line

• TFT Display LED pin → Breadboard 5V line


Connections from the TFT Display to arduino :

• TFT Display CS pin → Arduino pin 10

• TFT Display RST pin → Arduino pin 8

• TFT Display DC pin → Arduino pin 9

• TFT Display MOSI pin → Arduino pin 11

• TFT Display SCK pin → Arduino pin 13

• TFT Display MISO pin → Arduino pin 12
