video features yours truly explaining the basics of ultrasonic
range-finding sensors. If you ever want to add distance sensing, or
object/motion detection to your project, these sonar sensors are a great option. They're ultra-easy
to use, with an analog output (among a couple other output options), you
can get one distance-finding in no time. On top of their ease-of-use, I
really like the flexibility of these sensors. You can implement them
in both 3.3V and 5V systems (they operate from 2.5-5.5V), and the three
different output options mean you can almost always find a pin for them
on your microcontroller.
"Overall a great experience. The website is nice and clear, with plenty of useful information. The order process is simple, and the goods arrived quickly, in good condition. My daughter appreciated the magic tinkering beans too!"
