Circuit Documentation
Summary
The circuit in question is composed of an Arduino Nano microcontroller interfaced with several peripheral modules: a SIM800L GSM module, a GPS NEO 6M module, an AITrip ADXL335 GY-61 accelerometer, and an LM2596 step-down voltage regulator module. The Arduino Nano serves as the central processing unit, managing communications, sensor data acquisition, and power distribution. The SIM800L module enables GSM communication capabilities, the GPS NEO 6M provides location services, and the ADXL335 accelerometer measures acceleration in three axes. The LM2596 module steps down the input voltage to a level suitable for powering the components.
