Change in distance between closely spaced conductors will alter the capacitance between the conductors. Look at the comb structure just as two plates for simplicity. the two plates are separated by an air gap dictated by the manufacturing process. At any rate it is a very small gap. Due to inertia ( things wanting to stay at the same speed they are currently going)when the system moves the weight wants to stay in its current state more than the thin plate(s) it is attached to so in doing so it bends the plate ( or comb) it is attached to creating a difference in capacitance which is sensed electronically.Is this helpful?

I am wondering the same thing!

This was a long time ago, in a galaxy far far away. The technique is called photolithography and here is a good primer: ukposts.info/have/v-deo/aZKpmm-IiYyW1IU.html

+MrPolymath0 There'are a lot of phases as following: - Chemical Vapor Depositation ( at low pressures and high temperatures) o Epitaxial Growth - Etching of silicon parts in order to achieve the correct mass for the wanted resonance frequency ( taking into account non idealities due to under/over etching) --> Dry etching or wet etching - Dioxide Silicon Elimination using acids like HF. So in this way, it's possible to correctly obtain a moving mass which will be the inertial mass for the inertial forces detection. -Packaging ( at low pressure, obviously depending on requirements and budget), by means glass frit or eutectic bonding. etc etc. It may seem easy but it's far from it.

No you just need a voltage source, but an Arduino would be helpful to read in the data from the accelerometer

Or if you are a games developer you can use Unity for testing the accelerometer ;)

Since the structures are so small their resonant frequency (and hence oscillations) are very high in frequency, and your measurements would be lower than the resonant frequency. If you do hit resonance, it can destroy the accelerometer though, depending on the model. Some may have a 'hard stop' which prevents excessive deflection at resonance, and prevents damage from mechanical shock (i.e. 8 g accelerometers that can survive a 10,000 g shock)

lol

😂😂😂

Accelerometer would be better but both could be helpful. Look up a device called an IMU (Inertial Measurement Unit)

It will depend on the accelerometer. You'll have to check the datasheet. >100g to damage most I am sure.

If they can create solid insulators, via doping, then these can be used as limit stops to prevent shorts

If the velocity stays the same then the acceleration will be zero. So the accelerometer will read zero g.

@@Afrotechmods But when place an mobile on table it's velocity is zero but the accelerometer output is approximately 9.8m/s^2 in z -axis

@@DurgaPrasad-lp6vb That is because gravity provides a constant downwards acceleration force.

You can use an accelerometer to measure acceleration just fine. However one problem that some people encounter is trying to integrate acceleration to get velocity or position data, and in those scenarios accelerometer error does accumulate very quickly, so people tend to combine data with gyro & gps.

I've bought from them in the past and I find their stuff to be good value for money in general. They had no idea I was making this video.

Afrotechmods thanks for the swift reply, I'm sure you could have mentioned other vendors, it just seemed a teeny bit suspicous, with all the stuff going on and all, sorry for the nagging, fun video! :)

GizmoTheGreen "with all the stuff going on and all" Should I not buy from them?

sashablfc I think he was just worried I was doing paid product placement without disclosing so. They are fine to buy from.

Adafruit is the boss! Why would product placement be bad? Would that somehow reduce afrotechmods integrity? How is getting paid for hard work bad? Do you do all your work for free? I HOPE Adafruit pays him for product placement, so he has more incentive to make rediculamously fantawesomic videos!

Oi, I meant 'MEMS'.

😂😂

Hello, from the future

Hello from farther future

It's not the sensor , but the electronics and software that reads it that causes the delay. The data from the sensor is converted to digital data. Then it goes through software calculations to determine the angle , speed .. This causes a delay.

ZauStuv Sure!!

3.3v is a common digital devices voltage. I'm not sure of the origins or reasons it's used, though.

i guess that the reason is because some devices only have data lines with 3.3v volts like the Rpi, if you used 5v you will end up frying the gpio or the processor of the pi

thank you , but what is combed finger arrangement

This much i had since my schooling. *****​ wanted to know more.

Thank you though.. *****​

shubham saxena You can think of electricity like a river flowing downhill. The current is the cross sectional area of the river, so is the amount of water flowing at any given time. The voltage (also known as potential difference) is the difference in height of the river, so it is the amount of 'pushing force' behind the river's movement. To sum it up, the current is the amount of electrons moving while the voltage is the amount of force that is 'pushing' the electrons.

Ben Adamson​ thank you brother... Thanx a lot.... 😊😊😊😊😊

Ben Yarmis The outro was created by one of my Patrons who was kind enough to make it for free :) So it was his choice.

Afrotechmods CQ(seekyou?) would be more appropriate for an intro , QRT( basically the end of transmission) for the exit. BTW i watched enineeringuy's video on the topic last week, you both explainit well, but you had the die to show us

That's called a tilt sensor. Adafruit sells those too. Quick and dirty way for determining "is right side up" or "is not right side up."

The gyroscope uses the Coriolis effect combined with vibrating matrices at each axis. Basically the vibrations tend to stay in the same plane as the supporting structure of the proof mass. IIRC they still use changing capacitance but its the error of the vibrations which is really measured as this would indicated rotation about that axis.

No. The accelerometers are used to detect orientation. The Gyros give a turning "rate", which is really not very useful to detecting screen orientation by gravity.
