HARDWARE AND SOFTWARE

Microcontroller and Raspberry pi projects

In this project it will be shown how you can easily built up your own MagicMirror with voice control. You can learn to program your own MagicMirror modules and how you can write your own scripts for your voice commands. Feel free to use also other project ideas for e.g. smarthome solutions (switch of television or lights).

MagicMirror with voice control: Meine Arbeit

Equipment:

switch time socket e.g. here
raspberry pi 3b or higher, power adapter, SD-CARD, HDMI connector e.g. here
ultrasonic sensor HC-SR04 e.g. here
jumper wires e.g. here
some resistors
suitable case e.g. here
old monitor with optional VGA-HDMI adapter e.g. here
spy glass or foil e.g. here
USB sound card
microphone
speaker
wood for the frame
tape
soldering iron with solder

USEFUL SCRIPTS AND HINTS

US-SENSORSCRIPT FOR CONTROL THE HDMI PORT

import RPi.GPIO as GPIO
import time
import os

GPIO.setwarnings(False)

GPIO.setmode(GPIO.BOARD)

trigger = 16
echo = 11

GPIO.setup(trigger,GPIO.OUT)
GPIO.setup(echo, GPIO.IN)

def distance():
GPIO.output(trigger, True)
time.sleep (0.00001)
GPIO.output(trigger,False)

start=time.time()
stop=time.time()

while GPIO.input(echo)==0:
start=time.time()
while GPIO.input(echo)==1:
stop =time.time()

traveltime=stop-start
distance=(traveltime * 34300)/2

return distance

if __name__ == '__main__':
try:
while True:
abstand = distance()
print ("Measured distance = %.1f cm" % abstand)
if abstand > 100 or abstand < 10:
os.system("vcgencmd display_power 0")
else:
os.system("vcgencmd display_power 1")
time.sleep(300)
time.sleep(5)

resetten
except KeyboardInterrupt:
print("Measuring stopped by user")
GPIO.cleanup()

JARVIS TROUBLESHOOTING

If you get an error try that: https://github.com/alexylem/jarvis/issues/129

SUDO CRONTAB -E OR CRONTAB -E

Use only crontab -e [without sudo] to implement your Cronjobs

GPIO.BOARD VS GPIO.BCM VS WIRINGPI

Board= Pin numbering on the hardware device itself physical - starting with 1. To find out BCM and wPi use:= gpio readall in command window
