This course provides clear instructions for building an Arduino-based car parking assistant, which will allow you safe car parking in the garage. First, we explain the main two principles of the project: when there are objects or walls too close to the car and when there are no items or walls nearby. After that, you'll discover the hardware prerequisites, which include an ultrasonic sensor, buzzer, Arduino Nano, 9V battery, and connecting cables.

Next, the course investigates the ultrasonic sensor components, characteristics and functionality. You'll also find the equation for determining the distance between the sonar sensor and the object. The technique of crafting a schematic wiring diagram with Fritzing software is then covered. Following that, you'll get familiar with Arduino coding, discovering several areas for defining variables and constants and configuring the appropriate distance, among other tasks.

In the last section of the course, we discuss the steps involved in downloading and installing Arduino IDE and Fritzing, two software programs required to program the auto parking helper and to wire different components to form circuits. Lastly, we offer a brief overview of the Arduino and Fritzing user interfaces, including unique features, such as buttons for creating a new file, uploading a code and searching for items. This course is ideal for anyone interested in developing skills in electronics and microcontrollers.
