DIY - ARDUINO BASED CAR PARKING ASSISTANT

It seems like you've written a comprehensive guide on how to create a parking sensor system using an Arduino board. Here's a summary of the steps: 1. **Define Constants and Global Variables** * Define constants for pin numbers. * Declare global variables for LED pins, buzzer pin, counter, and distance. 2. **Setup Section** * Set up pin modes using `pinMode()` function. 3. **Function to Turn Off LEDs and Buzzer** * Create a function called `turnThemAllOff` that turns off all LEDs and the buzzer. 4. **Calculate Distance in Inches** * Read values from ultrasonic sensor. * Calculate distance in inches using the formula. 5. **Turn On/Off LEDs Based on Distance** * If distance is greater than 200, turn off all LEDs and buzzer (out of range). * If distance is between 55 and 200, turn on green LED. * If distance is between 15 and 55, turn on yellow LED. * If distance is less than 15, turn on red LED until it reaches 8 inches. * Start buzzer when distance becomes less than 8. 6. **Counter for Car Movement** * Compare `Distance` with `TempDistance`. * Increment counter if values are the same (object hasn't moved). * Reset counter to 0 if object moves. * Set `TempDistance` to value of `Distance`. 7. **Delay and Final Steps** * Add a delay at the end to pause code for a while. The final part of your guide is to demonstrate how the system works in real life. You've installed the unit in your garage, and as you walk close to the sensor, the light changes from green to yellow to red, and ultimately the buzzer goes on when you're too close to the sensor. This makes it easy for your partner to park the car without making any assumptions. Overall, this guide provides a clear and concise explanation of how to create a parking sensor system using an Arduino board. It covers all the necessary steps, from defining constants and global variables to setting up the pin modes and creating functions to turn off LEDs and buzzers. The code is well-structured and easy to follow, making it a great resource for anyone looking to build their own parking sensor system.
