Getting Started

Prerequisites

• Arduino board
• HC_SR04 sensors

• porting arduino code to arduino board

  • https://github.com/KKimj/HC-SR04

Installation

$ pip install HC-SR04

Usage

Import

from HC_SR04 import HC_SR04 as hc
from HC_SR04 import HC_SR04_fair as hc_fair

tmp = hc()
tmp_fair = hc_fair()

import HC_SR04

tmp = HC_SR04.HC_SR04()
tmp_fair = HC_SR04.HC_SR04_fair()

from HC_SR04 import HC_SR04_fair
from HC_SR04 import HC_SR04

tmp = HC_SR04()
tmp_fair = HC_SR04_fair()

Examples

from HC_SR04 import HC_SR04 as hc # single board with HC_SR04(1 to many)

my_arduino = hc(channel = 3, open=True) # if open is set True then open Serial connection, default open is False

print(my_arduino.get())

from HC_SR04 import HC_SR04_fair # single board with HC_SR04(1 to many)

my_arduino_fair = HC_SR04_fair(channel = 3, port_left = '/dev/ttyUSB3', port_right = '/dev/ttyUSB4')
# call open_serial() before using .get* method()
# or set open = True, e.g., my_arduino_fair = HC_SR04_fair(channel = 3, open = True)
my_arduino_fair.open_serial()

print(my_arduino_fair.get())
print(my_arduino_fair.get_leftside())
print(my_arduino_fair.get_left_sensors())

# print out status of instance
my_arduino_fair.test()
# switch left <-> right 
my_arduino.switch()
# print out status of instance
my_arduino_fair.test()

my_arduino_fair.close_serial()
