Wow! 100% on my Pi 4. This was an awesome little project.
This is by far the best tutorial for a power button. Very easy to do thanks very much
Simple , straight forward, like that. Thanks for this video it actually was more helpful than I first imagine.
Works on PI 4 in March 2023. Many thanks for all the hard work saving me loads....
Aw man. Seeing those RadioShack switches brings back memories. That was my first job right out of high school!
Aww yeah. I miss being able to run there to pick up a quick component or switch last minute-worth paying 5X the price :)
Radio shack was called Tandy in Australia back in the day.. Gone now.. Jaycar is my shop now when I need something right then.
Excellent video!!! I just bought the premade button from your website, and will complete the project!!! Also liked and subscribed!!!
M. Hannis Awesome! Glad you liked it, we’ll ship your buttons out today :)
Thank you for the tutorial! Very easy to follow along and it worked just like a charm.
Awesome!! Thanks so much for your scripting, your video and the detailed write up on your site. I just wired and installed on my Pi4 which is in vehicular use. Now, so much easier to shut down gracefully, with a physical button, instead of the GUI (or worse, turning off ignition key and hard-crashing the pi). I was prepared to copy and paste the code, run it at boot up etc etc. But your script did all the heavy lifting. Cheers!!!
Man that worked like a charm! Thanks for saving me from pulling my hair out🤣.
Tried older diys with no luck, then finally found this! Thank you sooooo much!!
No problem!
Thanks for the nice tutorial, now i was easily able to add the power button and status led to some pi3 and a pi4! thank you!
You legend. Thanks so much - this worked first go - super fast - super easy - THANKS SO MUCH
Great video! I tried it on raspberry zero W and it worked on first try!
Great instructive video howchoo! I've been looking for this to add to my Pi 4B for days. Works great. Thanks much for making this video.
No problem! Stay tuned for more :)
Super easy and it worked on my Pi4! Thanks so much
Great video, as the guy below stated, easy to follow and worked like a charm
Excellent tutorial! Simple to follow and no bs!
Aw, thanks so much! Glad you enjoyed it :)
WOOOOOOWW! THANK YOU VERY MUUUUUCH! Worked on first try :)
simple and worked without any extra hassle......great ! Thanks to you....
You're welcome!
Worked Great, I ran the code ahead of time, Thanks for the howto Video
Nice!! Thanks for share!!
Awesome work, man. Thank you a lot :D
Nice work, thank you! Works fine with my new Pi-Hole. 👍
Perfect!! My bartop is now 100% finished. Thank you 🙏🏼
No problem! Sounds like a cool project :)
@@Howchoo is usb3 speed still shafted on the 'new' firmware - I'm holding off on updates as All of the ones released so far have had other issues. I know it's a small risk but I'd reticent about bricking another one - having had one dev machine blowing it's hdmi 0 socket off from under-powering
Power Button: "Burrrrrrpp!!!!"
Me: I'm cutting you off!
Awesome video I got my rpi 4b on dec 25 and it worked no problem no need to get the latest version. Btw recommend turning off the pi through the interface like you would a regular laptop or pc but turning ot on worked no problem.
Great, thanks for the info!
Worked perfectly thanks!
This video should have a ton more views. Great video.
Thanks! All in good time ;)
Thank you! This works really well.
Managed to make it work with a switch rather than a button. followed your instructions carefully and it works! now I need to figure out how to turn off the fan
Hi! May I ask what type of switch did you use on your end? Will a rocker switch work?
@@kurtroyales2659 yes a 2 way rocker switch with 3 connection points
Obrigado! Fiz e deu super certo.
Thanks you so much. This video helped me a lot.
No problem! Glad it helped :)
clean and nice work!
Thanks!
Great video, thanks for sharing this. Is there an easy way to add a delay for shutdown? I’m using this in my vehicle and it has some interference. I figured if I add a .5 sec shutdown delay (hold the button for .5 sec) it will keep the noise from shutting down my PI.
I have implemented this on a Raspberry Pi 3 and it works very well. Kudos to you for very clear instructions. I have a question that perhaps you can help answer. Will this solution work to power down the pi running on battery power when the battery is running low? I am guessing that pin 5 will go logic low as battery runs out, effectively same as shorting with pin 6 (GND). Thank you 🙏
For a raspberry pi 4 you can now update from the Terminal so no need for the boot loader, but once you install everything do a reboot first and then the button turns off and on. Thanks for the tut 👍
with sudo apt update?
Great video - very clear and easy to follow. Thank you for sharing..
Is the button a momentary button..
Thank you so much!!
Hello,
Running Buster on a Pi 3b+, your script is the only one I got to work, thank you.
Question, is possible to add a "Hold" time in the script so the button has to be held down for x number seconds before shutting down. Many thanks.
Thanks for this wonderful howto video. I did it to my RPi3B and it works. I have a question though. Do you have a tutorial on how to add a serial (RS232) port on a RPi3B+? I need a communication port to control a serial modem.
Thank you for your script. Works great even on a Raspi 1 :)
I have a question. If we are already using Pin 5 for another thing like a controller, is there any way to change the pin settings for the button? Also great video!
Great video, thx
I think i will add a led if i do that, idk if it worth i but i like having visual that its "on" when using button like that
thanks helped a lot :)

See the full guide on howchoo: howchoo.com/g/mwnlytk3zmm/how-to-add-a-power-button-to-your-raspberry-pi
Thanks working great!
just one question, I've tried to change the script from PIN 3 to PIN 21,
now it only shuts down the pi and not waking it up.
any suggestions?
Great tutorial, thanks a lot. I was wondering how can I keep the host connection active even if I shut down the pi. PS. I am using Putty on Windows
CRACKING I love it I now if have my raspberry pi 4 in a *" fractal pc case "*
Using the cases power button to boot it up I will upload a video to my channel of it running off a power bank on my Sony 43 TV I LOVE IT with only 1 cable out of it witch is the HDMI cable
great, thank you
That's a 3d printed coffee cup!! :D nice vid.
Werry well explained man. Thank you verry much! The only thing i suggest is to get another case with bigger hight and position the button at the back nect to the sd card. This red button on your case loocks like an emergancy stop :)
Technicaly....10 points, design....2 points ;)
Haha thanks for the feedback!
awesome, works!
Good to hear!
Thanks for this, very helpful. My PI ws turning on and off fine but all of a sudden it only turns it off. It won't turn back on and a reboot command is the same, shuts off but won't come back on.
Hi, nice video, I am using the 7 inch touchscreen which utilises pins 5 and 6 already, is there an alternative pin out location i can use for the button?? TIA. Ian
The only two pins actually required for the touchscreen are 5V and GND - consider if your use case actually requires you to use any others - it might not.
Got it, i made a type fault, works perfect thank you👍👍👍👍👍
Excellent!
@@Howchoo does it switch the negative wire? Open and close
@@lucbisschops What do you mean? It doesn't matter which order the wires go; there's no polarity here.
@@Howchoo ahhh ok, thats my problem than i have a psu relais controle for my 3d printer on my raspberry aswel, and the ground was pluged in on the same place your ground for the killswitch was programed in your script, thats why, when i shut down my psu relais, the raspberry pi shuts down aswell, is there a way to rewrite the script for a different position of the gpio.
Thank you!!!!!
Do power cables that have switches built-in do the same thing basically? Great video, fun to watch.
Thanks! And not quite-using a power cable with a switch is the same as ripping the cord out of the wall. That physically cuts power without SAFELY shutting the Pi down, which is bad :)
:D same third hand , same soldering machine :D i just have blue one :D awesome one for its price
really good tutorial thanks. no idea why there are any thumbs down. only thing is, for me, I have 2 fans running on the same pin so will have to see if theres a way to move them or the button elsewhere?
Which pin are they running on? If it’s pin 5, this is definitely required for the power button’s “wake” functionality. But you can likely move your fan to another one (any other GPIO pin) since the fan probably only needs basic GPIO functionality :)
What kind of wire stripper do you use? I really liked that one
hi, thanks for showing. I have a question, can you do this with a touch (capacitive) button? By touching the button for 3 seconds? that would work and if so, how?
Can I use different pins? The ones you showed are occupied by a display I'm using.
This looks like a good solution for saving power on a RPi4 connected surveillance camera, but using a low power WiFi connected ESP32 (& motion detector) instead of a mechanical switch. Assuming that the RPi4 never really powers down, how much power does it use while in 'sleep' mode? Does it require a RTC battery to keep it 'alive'? Thanks😎
Quality.
Excellent Video......Thank you......I would like to use a button with an LED light ring. How can I use a flat metal actuator, surrounded by a green plastic LED ring. On the back there are 3 contacts for the button (common, normally-open and normally-closed) and 2 for the green LED ring (+ and -). Connect 3 to 6V to the LED and the Normal Open as in your video. My question is what would I connect the LED ring to on the board?
Did you ever find a solution for this. I would like to use a lighted button as well.
This works great. Just 2 things. 1). I get a message there is a resistor on GPIO3 when executing the script. 2). My Power does not fully go down. My Fan is still on although it looks like the USB ports are not active and of course the RED Led is still on.
But this does Stop (shutdown) and Restart when I push the button.
This worked great for my arcade cabinet power button until I needed to add a fan in 5v mode using pins 2 and 6. Can I use any other pins for a power button?
Hi! Good work!
Unfortunately, however, although following all the steps indicated, this scheme does not work on my Raspberry Pi B+ V1.2 (2014) either with regard to the led or the on/off button (cf. the other video). Do you have any suggestions that can help me?
Thanks in advance.
Will the raspberry also turn on when you re insert the power (usb) cable or can you just insert it and need to press the power button? Because I don’t want it to unnecessarily turn on when inserting power cable. Just like a normal computer for instance.
So does the button only work on sd cards that you have written this code to? So if you reflash your sd card with another software, you'd have to redo all these steps?
Does this work with other OS's like retropie, OSMC, or Kodi?
Hello! I'm currently planning out my first RPi project ever and I'm curious whether or not you know if there's a way to have it where you have to hold the button to shut down. With the project I'm planning, I'd imagine there's a chance of the button getting accidentally hit during use, so I want to mitigate this problem before it even begins. You wouldn't happy to have any thoughts regarding this, would you?
This could be done by forking and modifying the code-would require some knowledge of Python, but it can definitely be done :)
Which pins should I use when doing this with a 7" pi touch screen? Pin 6 is used as part of the wiring for that so are there alternatives I could use instead?
Awesome! I will use this for the arcade I'm working on. A question tho, Can I "unplug" the power cable after the script runs without any risk? Or the rpi stays on some kind of hibernation state?
I'm asking this because I have a main switch on the Arcade to cut off all the electricity. (for safety reasons AND because I'm using a CRT tv that I turn off/on like this) and I pretend to use the button/script first and then press the main switch.
Any thoughts?
Oh yeah you can totally cut the power after it shuts down safely. :) Just reconnect the power and it’ll boot right up.
@@Howchoo Great! So this is just what I need. Thanks you!!
Does it mean the shutdown script doesn’t perform a complete shutdown (power off) of the RPi?
Thank you for the video. can I install directly now without that bootloader thing because its been two years now. do these things updated now?
Yep, you don’t need the boot loader as long as you don’t somehow buy a super old Pi 4 that still has the original firmware (like old stock or something). Try skipping the firmware step and see if everything works. You can always do that step afterwards if needed.
Hi! THANKYOU!! Only 1 question; this is a "push" button or is the "click" button?
This video is so cool! TY.
I have a Q. why this pin now also works to turn on the Pi?
I found on internet that devs aded a wake up routine on bootloader on GPIO3.
Hey quick question, so if I am supplying power from an OBD2 adapter in my car, stepped down from 12v to 5v and then plugged directly into the usb port, if I run this script will it still shut down the pi? I am trying to think of ways around splicing a toggle into the obd cable. thanks!
Hi Howchoo, great and easy tutorial, however please help with one detail: I got the momentary NO button with 4 contacts (additional 2 contacts represent built-in LED functionality) - how should I connect /solder my button? Thanks for advice for anyone in this world. Cheers
I wish I had the answer to this, my Rpi 4 isn't working with this script and I don't know if it's the bootloader or the way I've soldered my button...
@@trispytreems I think you should be able to test your button with the instructions given between 02:07 - 02:28. Although the instructions are for a bit different thing (to detect if your button is a "normally open" or "normally closed" button), you can use the same style to detect which pins in your button are used for the button press if you try different pin combinations.
@@jarkko4732 just an update: it works now! All I had to do was do a Sudo apt get update then Sudo apt upgrade and it updated the bootloader.
Hey Zach! Love you channel, and appreciate all of your work.
Bist der beste ;-)
looking to add an LED on my Raspberry Pi 4b. Can I also add a raspberry pi fan as well? Or are the pins taken up by the button?
does ground need to be pin 6 or can it be any ground pin on the board? because 6 is already populated by a pwm cooling fan on mine.
I don't recommend stripping and soldering jumper wires, those are usually made of iron. It will corrode over time, specially that it would be exposed to the heat of the solder.
Use a regular stranded copper wire instead.
Download link says "Sorry, the file you have requested does not exist."
Great video, however why not use the gpio-shutdown overlay?
Yes, I'm wondering too, it seems easier. Is there some limitations with gpio-shutdown method ?
I have a raspberry pi 4 and the pi 7 inch touchscreen. it uses the same pins is there a way to add a power button to that setup?
I was able to get a power button installed on my setup
Thanks for the video. I have a pi4 and would like to do this with a touch power button.. is this possible. it has gnd / io / vcc ?
yes this should be possible if you wire the gnd to gnd, vcc to 5v available on the board, and io to pin 5
Hello can I connect 2 wires in the same gpio for the screen and the buttons ?
very new to linux, but i'm enjoying the learning... i tried this and got this back
/usr/local/bin/listen-for-shutdown.py:8: RuntimeWarning: A physical pull up resistor is fitted on this channel!
GPIO.setup(3, GPIO.IN, pull_up_down=GPIO.PUD_UP)
and the button does not work.
i'm using a 3b if that makes a difference
how has decided this problem? I heared we have to
solder two resistors so that there is no short circuit
From what I know, there are builtin pull-up resistors which basically prevents shorting pins when using a button. In this case I can only assume that its warning you about that, but I'm not 100% sure.
Great video, very clear and you helped me allot! I want to build it in a PC. Anybody knows if a power button and/or the reset button on a PC case is NO based?
I just tested the button in the chassi am putting my raspberry pi 4 in and it's a NO switch:)
@@KompositMormor thnx for the feedback bro! Imma try it my self then.
@@CheckitOutYaw Status update: Just tried the script and it works beautiful with the chassis built in start button:)
@@KompositMormor I use this with my raspberry pi 4b guided transparent LCD side panel (made my self). Its important that the raspi turns it self off along with the pc in a save way (preventing SD card corruption). Did you manage to turn your pc off and your raspi in the right sequence? Raspi first the ur pc? Now I just made a batch file to execute telling my raspi to shut down and then after my pc.
It should be, but it really depends on the case and its circuitry-the most reliable way to test it is to pick up a cheap multimeter and test for continuity (as I did in the video). They're invaluable to have either way.
Does this work with a regular non monetary NO switch? The pi is in a setup with a few other things that require a latching switch.
I did a similar project some time ago, the only problem with this is that if for example the script doesn't load for some reason or you load another image that doesn't have the script loaded and you push the button it may break the Pi, so it's safer to at least add a resistor to the switch or ideally make a pull up-down resistor circuit.
How would it break the Pi? Shorting GPIO3 to GND won’t do that
@@Howchoo I think I did it with gpio21. I don't know if gpio3 is different?
@@Howchoo But I believe the problem is that the pin stays at high voltage (3 or 5v) and doesn't use the internal push down or up resistor unless you enable it with the software.
Yea I just fried my board.... lame
@@jorgealejo1968 Ouch that sucks
Hi
I have an RTC module on my RPI 4 already using pin 5, may use an alternative pin for the power button? Thanks for your advice!
Unfortunately not -- does the RTC have to be on Pin 5 (SCL)? Shorting SCL to GND is required to wake the Pi; so you could use another pin, but you'd only be able to use it to shut down the Pi, not wake it.
@@Howchoo i dont want to start the pi with the button. how can i change it that it turns off on another pin
Hey I have octoprint on my pi3b+ I was wondering if this will work with my instance of octoprint or it will corrupt my pi
How do you do the software if you have a different operating system installed on the raspberry pi? I have Emteria OS installed on mine
Can I use pins 5 and 9 if I'm already using 4 and 6 for a fan etc?
Just wondering, is it fine to use one of the other earth pins? I'm already using 6 for a small fan. Thanks :)
Matthew Morgan Yep, you can use any ground.
@@Howchoo Thanks for the reply, great vid!
does your fan shut down with this? im curious
If I have a small case fan ground going into pin 6, can I just move it to another ground on the pi? Does it matter which ground?
You can use any other ground pin as well
Now, I think we can simply use "dtoverlay=gpio-shutdown" command in "/boot/config.txt" instead of this script. This script constantly shutdown my pi4 randomly while the 'dtoverlay' commande does not. Probably because of a debounce param missing, I guess.
Thanks anyway for sharing
It looks like the I/O connectors are too tall to clear the case. Did you shorten them somehow?
Howchoo quick question I have this script up and running but notice that if i plug anything usb while running it shuts down (sleep mode) but if I take off the connectors to the pins 5 and 6 and the script still running (basically no button connected there's no issue with it shutting down) I got better powerd adapter for pi and a powered usb Hub just to see if that was the problem and that is not the case still doing it? maybe if there is a way to edit the script to add a few seconds before shutting down? How do I edit a script? I really appreciate and help or advice Thank You :)
That’s super weird-double-check your connections, sounds like you might have a bad ground connection or bad button causing this to happen. :) as far as adding a delay, you can add a Python “sleep” in the core script you installed as part of the setup process.
In some other video it is explained to use some resistors not to damage the pins (breadboard and 4 pads button setup). Is this due to the button being used that you don't need anything but the button in your setup ?
This isn’t completely necessary-this is mainly to protect the Pi in case you accidentally connect the leads to the wrong pins. :)
@@Howchoo ok I see. Thanks for the answer
