Grace Musoki, another student participant, called on the government to ensure access to equipment and funding to help ...

Scientists have developed a new type of electronic "skin" that could give robots the ability to "feel" different tactile ...

Arduino Nano H C-SR04 ultrasonic sensor SG90 servo motor 1.8″ ST7735 Display (or equivalent) Soldering kit Screwdriver set 9V battery and connector Electrical wires and soldering gear.

The ultrasonic sensor sends a pulse and measures the reflection time. The ATmega32 calculates the distance based on the reflection time. The LCD displays the distance in cm. LEDs and buzzer respond ...

The Wireless Ultrasonic Radar described here is a scaled-down version of a true radar system. It utilises ultrasonic sound waves to detect nearby objects, presenting their precise distance (in cm) and ...

This Arduino-based Pomodoro timer project also uses this 25-minute cycle. Once you push the button to start the timer, it will run for 25 minutes, display a count-up timer and a "Study time!" ...

The code includes two Arduino libraries: one for the servo and another for the ultrasonic sensors. The main code is a simple 14-line piece with a simple if-else statement you can readily modify.

Theory An ultrasonic Sensor is a device used to measure the distance between the sensor and an object without physical contact. This device works based on time-to-distance conversion. Ultrasonic ...

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 ...
