Automatic Door Opening System
In Stock
An Automatic Door System using Arduino, an ultrasonic sensor, and a servo motor that detects an approaching object and opens the door automatically.
Description
The Automatic Door System is designed to open and close a door automatically based on the detection of an object or person using an ultrasonic sensor. The ultrasonic sensor measures the distance of an approaching object, and when the object is detected within a specific range (e.g., 15 cm), the Arduino sends a signal to the servo motor to open the door. After a set time or when the object moves away, the servo motor closes the door automatically.

An AND gate can be built using BC547 NPN transistors, a common general-purpose transistor used in digital circuits.
The circuit represents both the inputs A & B for the AND gate and Output, Q, which also has a +5V supply to the collector of the first transistor, which is connected in series to the second transistor, and an LED is connected to the emitter terminal of the second transistor. The inputs A & B are connected to the base terminal of Transistor 1 and Transistor 2, respectively, and the output Q goes to the positive terminal LED.

An XOR (Exclusive OR) gate is a digital logic gate that outputs true (1) only when the number of true inputs is odd. For two inputs, the output is high when the inputs are different. XOR gates can be constructed using basic logic gates or directly with transistors (BJT or MOSFET). Using transistors, we can design compact, efficient circuits for custom digital logic applications.
