Today we are going to make an Arduino-based sonar machine. This mini radar detects the distance and direction of the objects as well as a regular-sized radar. Stay tuned for our next episode!

He spun up an Arduino shield using this chip, and wrote the necessary code to interface directly with a commercial transducer. This is already a huge milestone for DIY sonar, but [Neumi] isn’t ...

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. This is a great use for a ...

After finding a ready-made sonar distance sensor online, they wondered if they could use it to help the visually ... It is powered by an Arduino Lilypad microprocessor, runs JAVA-like code written ...
