Raspberry Pi Distance Measurement

In this project we are going to interface HC-SR04 Ultrasonic sensor module to Raspberry Pi to measure distance. We have previously used Ultrasonic sensor with Raspberry Pi to build Obstacle Avoiding Robot

In this circuit, we used 8bit communication (D0-D7) to connect LCD with Raspberry Pi, however this is not a compulsory, we can also use 4-bit communication (D4-D7), but with 4 bit communication program becomes a bit complex for beginners so just go with 8 bit communication. Here we have connected 10 pins of LCD to Raspberry Pi in which 8 pins are data pins and 2 pins are control Pins.
