Hardware

hi folks,

i'm from germany and my english isn't fine, but maybee somebody here can help me.

i have a nybble with nyboard 1_2 - i namend him "chaos" - and wish me, he "life" like a cat, go around in my room, avoid obsticals, make catstuff, so what.

i'm an absolutely beginner in programming and calibrate nybble with petoi desktop app and loading up firmware.

with arduino ide and c++ i don't cope, nothing works... but with mind+ coding blocks it is better. i make a little crash-curs online in python.

the script here (https://www.petoi.camp/forum/software/make-nybble-run-around-at-home-and-avoid-obstacles?searchTerm=avoid) works fine - thanks for that! - (in the mind+ mode), chaos walk, sit and so forth, but he can't see and i don't now, how i should the ultrasonicsensor make work.

first i try so:

while True:

writeDigitalValue(6, 1)

time.sleep(1)

writeDigitalValue(6, 0)

time.sleep(1)

writeDigitalValue(6, 1)

time.sleep(1)

ultrasonic(readDigitalValue(6))

if (readDigitalValue(6))

print("yes")

else:

print("no")

the output is "yes", but only, when the trigger- and echopin is pin 6. with pin 7 for echo the output is "no". in the ultrasonic-mode the sensor works and the led blinks, but chaos no walk or make other action. the sensor is ok, i think.

in this reason i try it with the software from the pinpong-library in mind+ for the urm10-sensor.

i have written this code:

# -*- coding: UTF-8 -*-

# MindPlus

# Python

from pinpong.board import SR04_URM10

from pinpong.board import Board

from PetoiRobot import *

import time

openPort("COM8")

def pin6_read_digital():

class pin6_read_digital:

def __init__(self):

self.read_digital = None

def sonar_distance_cm():

global sonar_distance_cm

class sonar_distance_cm:

def __init__(self):

self.sonar_distance_cm = None

self.duration = start - end

self.start = time.time()

self.end = time.time()

self.TimeElapsed = end - start

def dis():

class dis:

def __init__(self):

self.dis = None

def __call__(self):

self.dis = None

def ultrasonic(read_digital):

pass

def TRIGGER_PIN():

pass

def ECHO_PIN():

pass

def pin6():

pass

def distance():

pass

def cm():

pass

def SR04_URM10():

pass

def sonar1():

pass

def read_digital():

pin6_read_digital

def Pin(TRIGGER_PIN, ECHO_PIN):

pass

def dis():

sonar_distance_cm()

def DigitalValue():

dis

readDigitalValue(6)

setattr(Pin, "D6", None)

TRIGGER_PIN = Pin.D6

ECHO_PIN = Pin.D6

setattr(pin6, "input", str)

while pin6.input(ECHO_PIN) == 0:

start = time.time()

setattr(pin6, "input", str)

while pin6.input(TRIGGER_PIN) == 1:

end = time.time()

start = time.time()

end = time.time()

distance = cm

sonar = SR04_URM10

duration = start - end

TimeElapsed = (end - start)

Pin(TRIGGER_PIN, ECHO_PIN)

ultrasonic(read_digital)

pin6()

distance()

cm()

SR04_URM10()

sonar1()

read_digital()

dis()

DigitalValue()

pin6_read_digital()

sonar_distance_cm()

while True:

dis = sonar_distance_cm()

writeDigitalValue(6, 1)

time.sleep(1)

writeDigitalValue(6, 0)

time.sleep(1)

writeDigitalValue(6, 1)

time.sleep(1)

ultrasonic(readDigitalValue(6))

ultrasonic(pin6_read_digital())

print("distance = %d cm"%dis)

the output is an error: print("distance = %d cm"%dis), %d format: a number is required, not sonar_distance_cm

ok, i now, in this line are placeholders and i try it with many numbers, for example 34300/2 or 17150 because of the speed of ultrasound, but the output is no distance who changes, is every this, what i wrote instead of "dis" in the last line of code. when i worte ("distance = %d cm"%1), the output is 1.

what exactly are the placeholders and what i must write there? i think, in the code are mistakes, are not? what must i change?

or give it an other way, nybble make randomly walk around home and see, avoid and so forth? maybee somebody has written a code and would share it?

thanks for reading and maybee help,

greetings from germany
