DIY Home Security - New Video: • DIY Simple PIR Motion ...
In this tutorial, we will learn how to make and use a flex sensor.
We will control servo motor with a flex sensor.
Flex sensors are passive resistive devices that can be used to detect bending or flexing. The flex sensor shown in this tutorial is a flex sensor that decreases its resistance in proportion to the amount it is bent in either direction.You can easily make a sensor wider and longer depending upon your project.
Required Materials:
- Paper
- Flexible Cardboard or Plastic
- Pencil
- Aluminum Foil or Aluminum Tape
- Wires
- Solder or Glue Gun

this is exactly what I'm looking for. Thank you so much! New sub here !!

@DjChamorro 7 лет назад

I've read in the comments below you obtained some different ranges. How could we improve this sensitivity? I'm really noob with this graphite thing hahaha I really want to learn more about this instrument. Ty

@alfredocalvimontes2488 7 лет назад

Hi, great work friend. I traied to do this for days, and i see other videos for make a flex sensor but i cant do this work. How do you do ? Same Tip ? And how do you measure the omnios? Can i do it with a tester or i have to pass energy to the circuit for it found ?

@theboytheycalljonny1 7 лет назад

Brilliant. Thanks! i

@LOKESHSBEE 7 лет назад

waiting for next video..... :)

@MDFRESCUER 7 лет назад

Good idea.

@milapravda3916 6 лет назад

Nice work and effort, but only two positions of the servo obtained. ON and OFF, not much in between. Some chimney soot (pure graphite) might offer more analog signal.

@nazariysamoylenko2320 7 лет назад

Great video! What kind of resistors do you use?

@mojojojo2624 6 лет назад

when you were gluing the sides did you use solder or hot glue

@LOKESHSBEE 7 лет назад

superb..........!!!!!!!!!!!

@kvlpnd 7 лет назад

This is a great idea. Gonna have to try it. Though I doubt about its sensitivity.

@kvlpnd 7 лет назад

@chaoshero223 5 лет назад

Amazing! Is this can create as 30cm x30 cm mat ? I want to create pressure mat

@Create_o_raptor 6 лет назад

what did u put in between the aluminum strips?? paper??

@gamestycoon7810 5 лет назад

Thanks

@zainubzehra6537 3 года назад

Can you please tell me the resistance range it showed from flat to fully bent position

@Create_o_raptor 6 лет назад

and can we use a flat metal wire instead of the aluminium strips??

@pasindugamage5777 7 лет назад

is this working? few years ago I design some flex sensors using copper sheets. bt that isn't work. I need to know if I use copper plate or sheet there can be a problem or not.

@akshitdudeja6550 7 лет назад

how have u attached the jumper wire to allumium sheet before putting glue using glue gun

@dalli_kaktus918 6 лет назад

tam aradığım kanal ama biraz geç buldum

@shaheenbarcha9193 7 лет назад

hey can you put a video for wireless control for robot using flex sensor

@paulpaute1591 5 лет назад

Se utiliza alguna bateria??? Para mover al servomotor?

@ayushkumar3679 6 лет назад

I tested the sensor using a multimeter and it gave any reading at all? Can you explain how? I don't have servos to test it now

@Md.NazmusSakib 4 года назад

Bro that was awesome! But how it works? How its resistance is lessening?

@GreenCarrotGaming 2 года назад

Can we use one wire (female to female wire) for the part at 2:16?

@hemeshchadalavada3430 6 лет назад

Can we use a 10k resistor there

@JamesHannagan 5 лет назад

Do you colour in one side of the paper or both sides with the pencil?

@SurfGamerz 2 года назад

Money saving one

@cowbra2740 6 лет назад

good video ! does it works with 10khm ?

@rishabhchopde6709 7 лет назад

Very informative. Is there a way to make the transition smoother (eg: 12° or 48°)?

@ahmedmuawiyah8985 5 лет назад

I have the same question.

@philpeep 5 лет назад

just map the results between 12 & 48 then? servoposition = map(flexposition, 0, 1023, 12, 48) servoposition = constrain(servoposition, 12, 48)

@PatchworxStudios 2 года назад

Hahahahaha

@janspoljar5123 6 лет назад

Hi im trying to make this flex sensor.And i made 3 diffrent sensors and none of them work.It's like it wont recognize their movement. Is it possible because i didnt color it enough?

@draggofishy8652 3 года назад

instead of hot silicone or solder can i use tape?

@jonnupe1645 7 лет назад

Would you have a video on using a flex sensor that controls a relay opening/closing? I'd like to use your example for a upcoming project

@liszcgsedt 5 лет назад

I assume you need to do something like "if val < x, write the pin triggering the servo high, otherwise keep it low". That is so easy even i could work it out, sorry. ;o)

@insideouteyes5572 5 лет назад

I may be out of the line here, but I think the graphite on the paper works as an electron transmission medium, when it is bent, the amount of surface area for electron transmission changes, and that changes the resistance. But as I said, I am presumptuous

@DudeBoerGaming 4 года назад

You are right. Graphite is conductive and in essense acts as a resistor. The more graphite, the less resistance and less sensitive.

@nickkarapas7564 7 лет назад

I cant understand how it works but........very good job....again new sub😊😊😊

@nickkarapas7564 7 лет назад

Οκ

@sramctc 5 лет назад

Wonder using graphite paper instead is better?

@chemgreec 7 лет назад

good video thank you..could you explain why the resistance varies when you flex it, i didnt get that part

@chemgreec 7 лет назад

hello..yes i understand the graphite part..what I dont understand is why the resistance changes when it bends? Why does the graphite resistance changes when bend? how does bending affects the resistance?

@gadgetguy2199 7 лет назад

love it

@user-pu9sj1rg7f 6 лет назад

Buna benzer sensörler geliştirebilir miyiz ?? Örneğin ıslaklık sensörünü yapabilir miyiz ?

@willyjimmy8881 6 лет назад

Can you make arduino controlled knuckle shaver?

@dhruvjyotidas3386 5 лет назад

which example circuit we have to do to check the readings ihave done the 2nd one but the sensor and servo always comming zero what should i do !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

@andresmendoza6939 6 лет назад

hola para la mano robotica necesito ponerle este codigo o el codigo de la mano sirve Para que funcione?

@mangapedia5564 4 года назад

The value of my flex sensor is fluctuating. In serial plotter it forms a wave like structure. What can I do?

@technocrat9984 7 лет назад

Im geting the sensor btween 0to 17,18 and servo is always 0what should I do now????

@Music-lv8xf 5 лет назад

what is that value of sensor? how did you get it???

@smaronboruah 7 лет назад

hey can you explain the working of that sensor?? and also...how does the circuit even complete? dosent the paper block the electricity?

@smaronboruah 7 лет назад

Mert Arduino and Tech thanks 😁

@ahmetkartalEEE 6 лет назад

Bende aluminyum folyola denedim ama flex sensörle servo motor kontrolu yapılmıyor sensor 1023 1018 arasında kendii otamatik değişiyor. Yaptığım sensörlerin hiç biri düzgün kontrol sağlamıyor. servo sürekli ufak ufak kendi halinde oynuyor bunu nasıl çözebilirim ?

@joemancino9049 6 лет назад

I’m getting about 20 megaohms when it is at rest, but can only get it down to about 4.5 megaohms...any ideas on how I can get it down to about 10 kilohms?

@joshuayoung8086 6 лет назад

@Mert Arduino and Tech Hi, when I tried this, my servo motor keeps moving in circles at 0 position. Note: I did not the aluminum part with the cardboard yet, I wanted to test out the flex sensor itself. Could that be why?

@joshuayoung8086 6 лет назад

I had the flex sensor reversed and I increased the range and it works fine now

@OscarGomez-fh6tl 7 лет назад

excellent video!! Could you use copper to replace aluminum?

@OscarGomez-fh6tl 7 лет назад

Thank you, I like the channel. Good videos are still good work.

@kristoftunner9199 7 лет назад

Hy! Awesome video, one question: How many ohm resistor did you use?

@vedantugale2646 2 года назад

@loriem2283 5 лет назад

Quick question: I saw another video that made flex sensors with aluminum can. Does it differ, like Will one work better than the other and why?

@traceparadox 5 лет назад

According to me this would work better than can

@wilbertpeniche9342 6 лет назад

Does the sensor only work while using arduino?

@AngrejSingh-vt7fn 4 года назад

sir pls comment how you checked the values of flex sensor

@RoadHater 4 года назад

The values fall when the sensor is messed with in any way and then rise again regardless afterwards. What is wrong?

@tanishvardhineni8744 7 лет назад

how many microns allumium foil u used

@jonaskorte6873 6 лет назад

Is this polarized or doesn't the polarity matter?

@julekhashaikh1285 6 лет назад

Can we use tape instead of hot glue??

@ultimatebuilder5987 7 лет назад

for what did you but the paper for

@ayushkumar3679 6 лет назад

what if I use more than one pencil rubbed strip??

@learachel4783 5 лет назад

What the resistor value that suit to this flex sensor? 1000ohm? Hopefully u reply my comment as i really want to know.. Its for my FYP ;-;

@tusharsood2443 6 лет назад

sir i am tushar from india i have a querry actualllly i was making flex sensor but i am unable to find flexible cardboard plz can u send me link fom where to buy flexiblble carboard

@trythis4758 7 лет назад

Great.But can i use aluminium foil insted of aluminium sheet coz i dont have sheet

@smaronboruah 7 лет назад

TRY THIS yes u can... it's fully okay

@talkshowlivehost3476 6 лет назад

Bro please telll me why you take the coad to the computer. But the coad is already there

@nohoney633 6 лет назад

Hi, thank you for video I made sensor and connected it to the board just like you, but it's not working, can I contact with you?

@lukegilardini578 3 года назад

I am having the same issue, did you resolve it?

@patrickczader3995 3 года назад

do you have to use it as an analog? or can you also use a digital pin

@nevermindaboutmyname7797 2 года назад

Analog

@ximeamarilla6928 11 месяцев назад

What program do you use in the min 4:14?

@user-ok4up8bm4t 6 лет назад

could u ues super glue instead of hot glue?

@yashmodi7535 4 года назад

i know that what are you trying to do. but, i don't understand that when you bend your flex band, how it will be creating close path between aluminium contact? and change in resistance is too far from your device.
