@@jamesfraser7394 I believe my problem was that I had the "key_pressed = cv2.waitKey(30)" statement and the two subsequent "if statements" indented too far to the right. Had pull the group back by one tab. I hope that helps.
Hi there That's because your camera won't turn on, so there's no picture Try to change this cap = cv2.VideoCapture(0, cv2.CAP_DSHOW) for this cap = cv2.VideoCapture(0) I hope it helped you
can you do a soft for card (like yugioh, magic ,pokemon) that add card show on camera to database with the number of card associate? that can be really itneresting
i use this motion on my program. i increase the value of threshold.sum to 1000 and even 9999 to verify if it work but still its sensitive to movement..what should i do?

Thank you. Can you recommend a tutorial on how to set up a camera with a computer that runs this code? Appreciate your help.
great explanation

thank you , can i have a hint how select different cam and send mail?
Anyone tell me how does he opens his camera/webcam in the video ?
thx a lot really interesting i will try it right now
Thanks
is there a video on how to set up our IDE to look like yours?
I am having a prob

any support is appreciated
Same problem here --> frame = imutils.resize(frame, width=500)
Figured it out. Tabbing error. Duh!

Really good video
You're really great 👍
when I write 'cv2.' it doesn't show me its options like VideoCapture(), but I write it manually and it works properly how to fix it?
works!, thanks!

How do u add python code into bulb?
There are Python libraries for smart bulbs. You connect to the bulb over wi-fi specifying it's IP address in Python code.@@alertsByJarvis

Bro first install in cmd
