we can imagine the portion with the leads mounted on a window frame and the magnetic activator portion mounted on the window proper. It will open a new window on your computer as a new USB device, you can ignore and close that window. There is also a separate magnetic activator which, when moved close to the switch will enable it. Connect the Raspberry Pi Pico to your computer while holding the BOTSET button at the same time so that it goes into bootloader mode to flash the firmware. In the picture that follows I have crimped two Dupont connectors onto the end of the leads for ease of connecting to the Pico. Our reed switch comes as the switch proper which is encased in a plastic mount with flying leads coming off it. Basically it’s a way of connecting an electrical circuit. ![]() ![]() While this is a pretty cool type of switch, it’s function is the same as a wide range of other switch types from a standard push-button to a lever type to simply pressing two wires together. ![]() When it is placed in close enough proximity to a magnet that has enough strength to trigger the required level of actuation, the metal reed bends and the switch is made. If you are looking to update using a mirrored. Luckily, Wiring Pi is included in standard Raspbian systems. The blades are positioned slightly apart in a sealed glass tube. This required users to download and install it. They are typically constructed of two thin, flexible, ferromagnetic metal wires or blades (these are the reason that the switch is called a ‘reed’ switch). Reed switches are type of switch that are actuated via the presence of a magnetic field. You can download it for free (or donate if you wish) from here. ![]() I've written this short explanation as part of the much larger book ' Raspberry Pi Pico Tips and Tricks '. Reading the state of a switch is a pretty basic function for a microcontroller, but it’s an action that is worth understanding and we can add a little bit of spice to it by using a switch that is commonly used in security systems and to detect the state of items that need to determine whether they are open or closed (fridges, laptops, washing machines).
