Project Simulation Test Schematic diagram below is from previous project. So, for a new project development that has been added a one more option which is flood sensor. Another ultrasonic sensor was added to be input component. Total ultrasonic sensor used is 2. Above picture displays the schematic diagram of this project. The ultrasonic sensor for flood and distance, IR sensor and vibration sensor serve as the input to the Arduino and the output signal is sent to the GSM and GPS module, based on the schematic. The LCD is used as the screen for this device to show the driver all the information about the car. Then, two buttons consisting of two separate functions are linked to the device. In order to start the engine of the car, the first button is used and the other button is for the emergency button. This software is used in a simple text form to compose the command program for the project. The Arduino IDE will write and burn compiler programs and supports C and C++ langu...
