This circuit integrates a variety of components including an Arduino UNO, an ESP8266 NodeMCU, a GPS module (NEO 6M), an LCD display, a potentiometer, an Adafruit ADXL335 accelerometer, and a SIM900A Mini GSM module. The Arduino UNO serves as the primary microcontroller, interfacing with the accelerometer for motion sensing, the GPS module for location tracking, the GSM module for cellular communication, and the LCD display for user interface. The ESP8266 NodeMCU is used for Wi-Fi connectivity. The potentiometer is used to adjust the contrast of the LCD display. Power distribution is managed across the components, and serial communication is established between the Arduino and the GPS and GSM modules.
