Sorry for the silly questions but I cannot seem to be able to google them. Lots of people complaining their "Android notification is/not flashing", etc...
I've recently bought a bag load of all sorts of electronics stuff. Really interesting stuff and good value but some of the components are not marked.
Please help identify, as the seller is not responding
In my tests, I supply power to the LED from a 5v DC source, via 1kOhm resistor.
1. I should have two "LED 5mm Flashing, RGB/Clear". By method of elimination, I've found two components that might be them.
They are clear-bodied and seem to have a tiny chip inside the LED.
However, when I connected them to test, the result was: continuous red light from the edge of the LED, cathode-side.
Perhaps 5v isn't the correct voltage to allow flashing?
Also, the position of the light is weird, why isn't it glowing from the centre of the LED?
2. In my "Integrated Circuits" baggy, there are two LED-looking components that don't do anything when connected to the source:
A. A black-bodied, opaque, LED-shaped component
B. A clear-bodied, LED-shaped component. There does not seem to be anything special inside the body. Really looks like a regular clear LED.
I do have two items missing from the "other components list":
"940 transmitter" and "photosensitive receiver" - could these be those (and any guess which is what)?
3. I could not find anything that might be it, on the lists provided. Let me first describe the component and provide pictures only if needed:
It's a torus (with square cross section) made out of something that looks like a magnet but is not actually magnetic. There are some wires looping around it and coming out from each side.
Wild guess - could be something related to radio?
4. I have two items on the "other components" list that I cannot find. I do have two items that don't seem to appear on any list:
The list items:
* Resistor - 56k Resistors Ladder
* AC Line Capacitor - 4n7 M Class X1, 440 VAC, Class Y2, 250 VAC
The loose items:
* A gray cuboid, ~5x12x15mm, two wires coming out. Says: mkp62 275 ~x2, 73k 40/110/56/B
* A yellow strip about the thickness of a ceramic capacitor, 8 pins, Says: 8x-2-560LF, B05501
