Setting Up HC-SR04 Ultrasonic Sensor and 16x2 LCD on BeagleBone Black
That sounds cool. To get started, you'll need to interface both the
HC-SR04 sensor and the 16x2 LCD screen with the BeagleBone Black. These are some steps to guide you
Wiring the HC-SR04 Sensor:
Connect the VCC pin of the HC-SR04 to the 5V pin on the BeagleBone Black.
Connect the GND pin to a ground (GND) pin on the BeagleBone Black.
Connect the Trig pin to a GPIO pin on the BeagleBone Black (e.g., P9_12).
Connect the Echo pin to another GPIO pin (e.g., P9_15).
Wiring the 16x2 LCD Screen:
Connect the VCC pin of the LCD to the 5V pin on the BeagleBone Black.
Connect the GND pin to a ground (GND) pin on the BeagleBone Black.
Connect the RS, RW, E, and data pins (D4-D7) to GPIO pins on the BeagleBone Black (e.g., P8_11, P8_12, P8_13, P8_14, P8_15, P8_16, P8_17).
Libraries and Software:
Install necessary libraries for GPIO control and LCD display.
Write a Python script to control the HC-SR04 and LCD.12 replies
