Ultrasonic Distance Measurement- Serial Monitor
In Stock
A Ultrasonic Distance Measurement System using Arduino and an ultrasonic sensor that calculates the distance of an object based on the reflection time of ultrasonic waves and displays the result on the serial monitor.
Description
The Ultrasonic Distance Measurement System uses an Arduino and an ultrasonic sensor (such as HC-SR04) to measure the distance of an object. The ultrasonic sensor emits ultrasonic waves and calculates the time taken for the waves to reflect back from the object. The Arduino processes this time and converts it into a distance value using the speed of sound. The measured distance is displayed in real-time on the Arduino serial monitor, providing an accurate and simple way to measure distances.

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 Automatic Room Cooling is an electronic system designed to maintain a comfortable room temperature automatically. It uses a DHT11 temperature sensor to monitor the room, a DC fan for cooling, an LCD to display real-time data, and a buzzer to provide alerts. The system activates the fan automatically when the room temperature exceeds a set threshold, making it an efficient solution for homes, laboratories, and small offices.
