- Just another basic circuit this time using potentiometers, this circuit doesn't use any complicated code in fact it's basically just one line "turning on" the digital pin. If you have any questions or suggestions please leave them below!

(1.) Hi, there.
(2.) New to electronics.
(3.) Where did you buy those trimmer pots { potentiometers, variable resistors }? Seem pretty secure and sturdy, with a high-enough, easy-to-adjust { grip and turn } dial.
(4.) Alternatively, would you know how to secure a dial to the ones that have the flat tops, where you need a paper clip, flathead screwdriver, or fuse leg lead in order to turn/adjust it?
(5.) Also, do have some of the completely blue ones with the attached dial, but the legs are thin, causing the whole component to be flimsy and become dislodged on the breadboard.
(6.) To make the thin legs on the full-blue VRs more “secure” (plus other things that won’t always stay put, like switches), sometimes insert one or more staple(s) or super-fine sewing needles to remove the extra space, but would just rather have a component that inserts and then that be the end of it.
(7.) What are the value and voltage for your resistor?
(8.) For your LED, which voltage and mm size did you use?
(9.) Thanks.
(10.) Toodles!
Hi!
First off sorry it took me awhile to respond and I am also new to electronics so I'm not sure how helpful I can be, but I will try my best.
1. I got the potentiometers from the IOT bundle from Arduino as well as everything else in the video.
2. not sure, maybe you could 3d print something or hot/super glue?
3. I don't think I have any completely blue flimsy potentiometers in the bundle
4. 220 ohm resistor
5. this LED should have a typical forward voltage of 3.2v not sure what mm size means... I have all these details in the previous video as well as links to some helpful diagrams and resources I have found if you are interested. Hopefully this helps!
