Ultrasonic fingerprint scanners aren’t the only option if you want to hide the sensor in the display. Optical-capacitive fingerprint scanners are being used for this purpose too. The industry is ...

The HC-SR04 ultrasonic sensor uses SONAR to determine the distance of an object just like the bats do. It offers excellent non-contact range detection with high accuracy and stable readings in an easy ...

The project is equipped with a DHT11 sensor to read the room's temperature and an LCD to display this temperature reading and the speed the motor is currently running at.

In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...

This project combines Arduino and Processing to create a radar-like visualization of distance measurements. The Arduino code reads data from an ultrasonic sensor and a servo motor, while the ...

To test the Me Ultrasonic Sensor, we’ve written a program that follows these conditions: If the Ultrasonic Sensor detects objects less than 10 centimeters away, motor 1 will rotate at 100% speed. if ...

code: // C++ code // include the library code: #include // initialize the library with the numbers of the interface pins LiquidCrystal lcd(12, 11, 5, 4, 3, 2); int ultrasonic = 0; long ...

Arduino UNO circuit board [8] and an HC-SR04 ultrasonic distance sensor [9] were used for data collection and are shown in Figure 2. Arduino UNO was placed on upper face of top plate and ultrasonic ...
