ST’s EVLSERVO1, a turnkey reference platform for servo motor control, enables sensorless or sensored field-oriented control (FOC) with one, two, or three shunts. It drives three-phase brushless motors ...

Circuit: Ultrasonic Directive Speaker Back in 2011, Elektor presented a DIY 50-m range directive sound beam using an array of piezo ultrasonic transducers (up to 200) driven with a PWM signal. While ...

This project is a car parking sensor system that helps drivers detect obstacles and avoid collisions while parking. The system uses an ultrasonic sensor to measure the distance between the car and an ...

This paper presents an equivalent circuit model of an asymmetric disc-type ultrasonic motor and discusses its applications in the evaluation of the motor's characteristics. The modeling process is ...

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 ...

For those starting out in Arduino, there are tons of resources to get better acquainted with the community and the types of projects you can tinker with.

Maker Uno RP2040 review with Arduino IDE using micro servo, soil moisture sensor, ultrasonic sensor, and I2C OLED modules Today, We will review the Cytron Maker Uno RP2040 development board combining ...

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.

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 ...
