HC-SR04 Ultrasonic Range Sensor on the Raspberry Pi

Ultrasonic Distance Sensors. The sensor output signal (ECHO) on the HC-SR04 is rated at 5V. However, the input pin on the Raspberry Pi GPIO is rated at 3.3V. Sending a 5V signal into that unprotected 3.3V input port could damage your GPIO pins, which is something we want to avoid! We'll need to use a small voltage divider circuit,
