We don’t know if [Hanna Yatco] has a good sense of balance or not, but we do know her Arduino does. Her build uses the ubiquitous HC-SR04 SONAR sensor and a servo.

Here, in this tutorial we are going to show you how to use a Servo motor wirelessly with an Arduino UNO and an Android device via Bluetooth connection. We already controlled servo with Arduino, this ...

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 ...

ABSTRACT: In this study, a simple Arduino-based experiment was designed to examine the acceleration of the object during free fall and to calculate the value of “g” (acceleration due to gravity).
