Turn off/on display with phyton.

[tfsnchez]

Hi.

I need desing a solution for a IoT. Need turn on/off display with a raspberry 3, but I dont have any idea how I can do it.

In summary I have a card reader connected to my door, and need to turn on my screem in my rasp when people made a check in my card reader.

If some people here could help me.

I don't know how to do it but presumably something like a mobile phone where you can wake it up with a couple of taps on a touch screen and then it goes back to 'sleep' after a period of no activity?

Yes sure, In that case, I need to turn on, when people make a check in.

Please give us a datasheet or at least a link to the
product page of the display.

thanks for you response, for more details I made a diagram about my project.

I think they think that you are talking about some unusual sort of display but it appears you have an ordinary hdmi device. The tvservice program can be run to turn normal hdmi and composite pi screens on and off.

I would create a function to do this and directly use this program in the function to start out with at least so I could get it going. If you put this inside a function, you can later easily go in and change how you are turning screens on and off, the means can be different on different hardware and operating systems. If you strew calls to this program all over your program and later find out you have a better way or that your hardware is suddenly different, you'll have to hunt them all down.
