Double check the wiring to make sure you do not ever connect the GPIO pins to 5V. The GPIO pins should never be connected to anything higher than 3.3V. The LED is powered from the Pi’s 5V supply. Remember that GPIO numbers are different to physical Pin numbers. Two connections were required for the LED and two for the switch which is used to change the state of a GPIO pin. It was designed for 12V but the red LED inside works fine with 3.3V or 5V. The switch/button I used was an automotive momentary action device with an illuminated power symbol. This avoids any accidental shutdowns especially if the system is being used by curious children. This allows you to hold it down and only trigger the shutdown if it has been held for a certain number of seconds. You can use any momentary action switch for this project. Using a separate switch on the side ensured it wasn’t accidentally activated while playing games with the main player buttons.Īlthough this guide is especially relevant to RetroPie systems it could be used in any Raspberry Pi project. I decided to implement a shutdown button on my IKEA arcade table to make it easier for kids to correctly shutdown the system without needing to mess around in the menus.
#HOW TO INSTALL RETROPIE WITH OUT IMAGE UPGRADE#
It’s probably the most useful upgrade you can make to a Pi gaming system. All you need is a basic momentary action switch, some wiring and a simple Python script. This tutorial explains how you can do this via a shutdown button connected to the Raspberry Pi’s GPIO header. Shutting down RetroPie usually requires the use of a menu in the Emulation Station interface.
