To supply targeting data for the launcher, an Arduino Uno uses an ultrasonic sensor pair mounted atop a servo. As the servo rotates, the returns from the ultrasonic sensor are plotted on a screen ...

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 ...

The joystick is used to rotate the servo motor left and right. Mounted on top of the servo is an ultrasonic sensor, which rotates with the servo to scan different directions. If the ultrasonic sensor ...

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 research aims to develop a RADAR system using an ultrasonic sensor (HC-SR04), servo motor (SG90), and Arduino UNO. This RADAR system can detect objects in the vicinity and display information ...

The electronics are fairly straight forward, consisting of an Arduino, WAV shield, PIR motion sensor, servo motor for the jaw, and a couple of red LEDs for the eyes.
