Basic starter set of components

One thought that comes to mind is some of the Arduino and Raspberry Pi started kits that Amazon stocks. They usually come with the board and an assortment of LEDs, resistors, switches, sensors, and displays, and are generally priced very competitively.

Amazon is also a great place for things like resistor and capacitor and transistor kits, which include assortments of the most popular values. Again these are reasonably priced and most of them come packed in a plastic storage box to keep them sorted.  A lot of my workshop parts originate from those kits.

One of my favorite stores is Pimoroni in the UK, they have their Maker Essentials series of parts that you may find useful.

Hope that is of some help.

Jameco (www.jameco.com)

EvilMadScientist (www.evilmadscientist.com)

Adafruit and SparkFun have good product descriptions and tutorials. Jameco and EvilMadScientist are based in California, and I get my orders from them quickly. EvilMadScientist has a great selection of LEDs. When you order LEDs, you get resistors (your choice of values) free.  

For components like transistors and mosfets i usually search on aliexpress.com or wish.com

you may have too wait 3 or 4 weeks untill it arives but you can find a lot of different sets for low prices and sometimes in handy storage boxes. Once I ordered 1000 resisitors for only €2,- 

I even ordered an Arduino Mega + Wifi clone and an Arduino Uno + Wifi clone, and they work like they should, but watch out for rubish, some things are badly made or even fake. 

Thanks all of you, but individual parts are easy. What I was looking for was a set with a little of everything. The Arduino I have and the transistors and capacitors that came those sets. I want a larger assortment of  electronic parts.

various transistors, mosfets, capacitors and coils

Some of these are easy, some of these are kindof hard.

The easy ones: You can get resistor, capacitor, transistor, diode and LED kits that will give you a pretty nice variety. Any random "ELEGOO upgraded electronics fun kit" or similar search on amazon, ebay, or elsewhere will get you a small pile of these components.

Beyond that, the reason people don't offer an all-in-one-kit is that it kindof depends on what you're doing. Did you have some specific projects in mind? Mosfets and coils (which coils... do you mean ring inductors?) are somewhat specialized, and you don't really see them in mixed kits.

If you're thinking of doing the kinds of projects Bill does on the channel, I actually suspect the lack of sensors is what you'll want to fix first. You can get "47 in 1" and "35 in 1" arduino sensor kits that can help you get started there, though.

I originally had this comment in my previous post here, then took it out, then put it back in, then took it out again... and having read another thread, have decided to put it back.

One issue you may want to consider when putting together your initial electronics kit is quality. The three links I put in the previous post are cheap, in both senses of the word. The resistors will usually be within 20% of their target rating, the capacitors will often be within 50%. This can actually be perfectly workable for small experiments, but can be very frustrating when trying to make "real circuits".

If I was starting over again, I would not buy resistors with a tolerance outside of 1%. (Capacitors are more finicky, but 5-10% is 'high quality' depending on type) Sure, they're a bit more expensive, but it's just so much easier than dealing with odd surprises. I have discovered that measuring each component as you assemble your circuit doesn't always solve the issue due to temperature sensitivity curves. A small heated chamber and an RC-circuit plugged into an oscilloscope can be eye-opening.

The big, high-quality vendor for most of us is going to be digikey. The issue, of course, is that the prices are also quite a bit higher. So far, I've done most of my bench work with the cheap stuff, and the few projects I've done where maintenance/repair/replacement will be difficult (plus a handful working directly with mains voltage), I've ordered parts specifically for that project from digikey.

To directly answer your question, however, you're not going to find a useful multi-component kit from digikey.
