Hiya Karen, my current project with an Accelerometer is a dog collar/harness with WS2812b strip LEDS that show how and where the dog is moving along. Red=left side, green = right side and White in front, with changes in display as it moves.

@@maker_karen1785 The Sides, Red + Green Go up and down like a VU meter as his direction changes and accelerates, while the Front, White, adds rows of white across his chest and get brighter as he picks up speed. It is a big loop around his neck, one strip divided into groups, and I might add small side bars to extend the Red/Green

Airpods have optical sensors on each side that are able to detect when they are in your ear. The tapping function is measured by accelerometers.

In wearables this could be used to attain positive, or correct, body positions: fix slouching, improve dance posture, public speaking problems, athletes stance and movement (track a pitcher or QB's throw) or monitor physical therapy progress in real time, sense a sleep driver, feedback for a fit app, detect an infant in vulnerable sleeping position, use for location finding, map tracking, direction for hikers, Alzheimer's patients, and more.

The duck hunt game, uses a light gun. in the arcade and home versions they use light sensors on a progressive strobe onscreen to determine what segment of the screen that was being pointed at, and not accelerometers. Although I'm not familiar with the specific one he was using in his segment, it strongly resembles the nintendo home light gun.

It works even simpler like that. Electronic pens had accurate time sensing like you describe. The NES gun is super dumb tech, it is just a photodiode with a lens. The screen turns black when you pull the trigger, with a small white square remaining on the place of the duck. So if the light drops on the photodiode in the gun you have missed, if it keeps seeing a bright spot you have a hit. With 2 birds there are 2 black frames in succession so it can tell which bird is hit. 4 birds would be near impossible as you will get very long black frames. That was probably the reason it wasn't used much. A game like Terminator or Commando would be impossible with the tech.

Most of the use is for the gyroscope (see your own examples), not the accelerometer. How do they make that one on a tiny scale? Totally curious about that. And the NES gun is a BAD example. It has nothing to do with accelerometers nor gyroscopes. It is a photodiode that measures whether there is light at the position of the duck in the blackout frame you hardly see when you pull the trigger.

8:43 Wrong. That is a gyro sensor that sometimes work in pair with an acc.sensor. Acc. sensors are logical but gyro sensors are not. They are based on Faradays paradox, that even Einstein did not get and was unable to explain. In aircraft they were first based on rotating gyros, then lasers in a box the finally the invention of the modern gyro sensor, that is based on really weird science that even work in space.

I use "Gyroscope" in my micro:bit tutorials because of that. Most libraries deliver X,Y,Z rotation, and then students start to treat it as acceleration in their code. They freak out. I now say the micro:bit has a gyroscope and the code challenges make way more sense. Maybe it is time for the micro:bit organisation to change the small print on the bit itself to orientation/direction sensor or something like that.
