How to Control a Servo with an Ultrasonic Sensor and Arduino + Code

Video Description

Ready to make your Arduino projects interactive? Join me as I show you how to control a servo motor using an ultrasonic sensor and Arduino. We'll wire all the components together, dive into the code with line-by-line explanations, and explore two fun examples: a servo snapping to attention where the servo rotates to a specific angle when an object is detected at a specific distance and a dynamic setup where the servo rotates smoothly from 0° to 180° based on how close or far the object is. Whether you're building props, a robotic arm, displays, or just want to add some interactivity to your Arduino projects and props, this Arduino tutorial is packed with possibilities! 🔗 Full Tutorial & Code: http://racheldebarros.com/how-to-control-a-servo-with-an-ultrasonic-sensor-and-arduino/ ▶️ Get Started with Ultrasonic Sensors and Arduino: https://www.youtube.com/watch?v=ZqQgxgnH9wg 🤖 WANT MORE Arduino projects with wiring diagrams and code?

Your support helps me create more content like this! ---------------------------- Some links here (Amazon) might earn me enough nuts and bolts (aka commission) to keep the LEDs blinking and servos turning. No extra cost to you, just a lil' fuel for my caffeine-powered nights of DIY-ing and passing on what I learn to all of you. I only feature stuff that's survived my "Did-it-Explode?" test. Build on, and thanks for the recharge! #arduino #ultrasonicsensor #servo #servomotor #arduinocode #arduinoproject #arduinotutorial #arduinoprogramming
