Setting up the hardware
As just stated, in this project we're trying to implement two different setups: the first one uses the analog output of the ultrasonic sensor and implements a circuitry, where all the devices are directly connected with the BeagleBone Black (all peripherals are near the board); on the other hand, the second setup allows us to remotely manage the ultrasonic sensor by using an USB connection, so we can mount the sensor far from the BeagleBone Black board.
Simply speaking, we can put the sensor in one place while the LEDs are in a different location, maybe in a more visible position, as shown in the following image:
