Raspberry Pi — Smart Pss

Tired of playing the "is there a spot?" guessing game every time you pull into your driveway or garage? What if your car could tell you—before you even turn the corner—exactly which spot is free?

def get_distance(): GPIO.output(TRIG, False) time.sleep(0.2) GPIO.output(TRIG, True) time.sleep(0.00001) GPIO.output(TRIG, False) Tired of playing the "is there a spot

⚠️ The HC-SR04 ECHO pin outputs 5V. Use a voltage divider (two resistors) to step it down to 3.3V, or use a logic level converter to avoid frying your Pi. Step 2: Write the Python Script Here’s a simple, production-ready script: False) time.sleep(0.2) GPIO.output(TRIG
