The Arduino Motion Sensor is a tiny, tiny sensor.
And it’s not just any tiny sensor, it’s an Arduino motion sensor that will detect the movement of the fingers, as well as the movement in the surrounding space, according to Arduino.
The sensor measures a single line of code.
The Arduino will send a signal from your Arduino to your smartphone or tablet via Bluetooth to send a picture of your fingers.
The camera on your smartphone and tablet takes the picture and then it feeds it into the Arduino.
And you don’t even need a fancy Arduino board to use this sensor.
The Motion Sensor only requires one Arduino microcontroller and an Arduino Mega.
It’s so small, it barely fits into your pocket.
That said, you can do some pretty cool things with this sensor using it.
For example, you could capture videos of your own fingers and play back them as a soundtrack.
Or you could use the sensor to capture the movement or movement of objects you’re viewing.
There’s also an example of how to use the Arduino motion sensors in your home, as a way to help you teach your kids about physics and electronics.
If you’ve ever wanted to turn an Arduino into a super-powerful motion sensor, you’ll love this guide on how to do it.
