IN,pull_up_down Lesson 11 Reed Switch¶ Introduction. Required Components. 1 * Breadboard . We actually tested this with a Cytron Maker Pi Pico We will use Micropython for these examples but of course you can use the Arduino IDE as well if you have Raspberry Pi Pico support enabled Oct 27, 2022 · Reed Switches with the Raspberry Pi Pico. The principle of operation of a reed switch is very simple. Beginners. It was invented by Walter B. BOARD) #variables: reedIn=40 #reed relay from rimco medLobOut=38 #for controlling relay for external output x=0 #counting how many times reed relay has switched #setup the pins: GPIO. 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). com/HallSwitchMono. When a magnet comes near the switch, its internal contacts close, completing an electrical circuit. You can buy the kit and perform some other operations as well. What You’ll Need 19 hours ago · Next, you’ll need to wire the reed switch correctly to a Raspberry Pi GPIO pin using a reliable pull-up or pull-down resistor to guarantee stable signal detection. Reed Switch with Raspberry Pi: Reed Switch with Raspberry Pi– A very simple, but quite useful sensor is the reed switch or contact. This solution would also work with an ESP8266/ESP32 type device instead of the Pi Zero and it how existing open source project such as ESPHome work. Hall sensors are generally used to measure the speed of intelligent vehicles and count in assembly lines, while reed switches are often used to detect the existence of a magnetic field. Buzzer – 1 4.
