Instructions
A reed switch is a passive electronic contact element with advantages such as simple structure, small size, and easy control. Its housing is usually a sealed glass tube. It contains two flexible iron reed switches (also known as rhodium metal reeds) filled with an inert gas. Normally, the two glass tubes, made of a special material, are separated. When a magnetic material is near the glass tubes, the two reed switches are magnetized and attracted to each other under the influence of magnetic lines of force, forming a circuit between the connection points. When the external magnetic force disappears, the two reed switches separate due to their elasticity, thus breaking the circuit. Therefore, the reed electrodes, used as signals to control the magnetic field switching device, can be used as sensors for counting, distance, etc. (in security systems, mainly for door magnetic sensors, window magnetic sensors, etc.), and are also widely used in various communication devices. In practical applications, a permanent magnet is usually used to control the on/off state of the two metal plates; this is also called a "magnetic rectifier." Circuit Diagram: Source Code: Arduino Test Program Connected to D0 (Example): Arduino Test Program Connected to D0 (Example): int Led = 13; // Define LED interface int buttonpin = 3; // Define reed sensor interface int val. // Define digital variable val void setup() { PinMode (Led, OUTPUT); // Define LED output interface PinMode (buttonpin, INPUT); // Define reed sensor as input interface } void loop() { Val = digitalRead (pin); // Read the value of digital interface 3 If (val == LOW) // When the reed sensor has a signal, the LED lights up { DigitalWrite (Led, HIGH); } Otherwise { DigitalWrite (Led, LOW);
