After talking with Daniel, I find that it is because the resistor I am using is to small…
I change to 10M and it works!
different values I get
Yes, for the next step I will going to sew them on the fabric and wear it to see the value. This way I may be able to differentiate between wearing it on my body and wearing it on my body and touching it with my hands.🙌]
With Daniel’s help. I get the optic fiber and other materials🥳
I tried the optic fiber, and I understood why Daniel told me that I might need some sandpaper.
The brightest part is the end of the fiber, but there is almost no brightness in the middle of the fiber.🧐
I looked at the sources Daniel gave me and find there are different types of optic fibers: https://www.instructables.com/The-Beginners-Guide-to-Fiber-Optics/
Side glow fibers can achieve the effect that the whole fiber is glowing. But for the end glow fiber, pretty like its name, only the end will be bright.
I use the sandpaper to sand the side of the fiber optic.
