If learning transistor and amplifier theory, then other parts would be useful, though beyond the scope of this post. The previous are mainly for turning loads on/off. Though ceramic disc caps are fine for bypass capacitors, they suck for analog circuits that tend to do better with better types of caps. Most kits will likely include crappy 20% ceramic disc caps for lower values. Minimum trimpot or pots (variable resistance):ġnF, 10nF, 100nF, 1uF, 10uF, 100uF, 1000uF.ĥ% film caps for lower values, 20% aluminum electrolytic caps for higher values. For capacitors, most newbie project likely only need in the range of 1nF to 1000uF, though it wouldn't hurt any one to have from 1pF to 10000uF. Though it's more of a pain, technically a person can get buy with fewer values of resistors, then series or parallel them to get other values, or attach a trimmer or pot to a fixed-value resistor to adjust them within a range of resistance values.įor resistors, most newbie projects likely only need in the range of 100 ohm to 1M ohm, though it won't hurt any one to have values from 0.1 ohm to 10M ohm. ![]() Whether you buy these individually or buy a kit, make sure they include a wide range of useful values. ![]() When it comes to resistors / capacitors / inductors, you should keep the following in mind about the available values:įor resistors and capacitors, I recommend that everyone start with powers of 10 of e-series numbers. If you can't find something, then reply to this post on Wednesday (because of Xmas with family). Sometime prices go up/down on EBAY, so you should search again with a similar title to determine if you can get same item cheaper from another seller. Here is a long post that I wrote 3 weeks ago. One person might want more individual electronic parts, while another person might want more board modules, another person might want more surface mount parts, basically just too darn many things and too many choices. It's hard for any kit to cover everything. Many kits are way over priced compared to the price of the parts that you can purchase from asia. You mainly save time by purchasing a kit. You say "Just use a Y(a common item everyone has, yes?) and maybe a Z(less common, but surely you have one available?) that will for sure solve your problem/be what you need."Įdit 2: A different place to ask this question is also a valid answer. ![]() Thus, I am looking for really generalized advice, on where/what would be the must need/where to get items for basic electrical/hardware tinkering?Įdit: Another way to look at my question: I am fully aware that different projects will require different hardware/components, but also don't want to be needlessly held back by not having 'basics everyone doing these things should have.' I have just purchased an arduino, but, looking beyong the projects that come with it, I am wondering where would be the best place to get a generic, covers-as-much-of-the-basics-as-you-can kit, ie common resistors, a couple of leds, breadboard, etc I honestly don't even know enough to know what to ask. I am just getting into electronics, and want to teach my son. ![]() Hi, I am relatively new to Arduino, but an original RPi owner, and a Linux lover, and half buttocked programmer.
