Hello,
So I am trying to find some useful electric stuff, and I did, but I want to know from the community if there is an item, other than basic electric stuff such as shields, multimeter and what you get in the Arduino starter kit, that proved helpful to you in your projects?
some pins, solder machine, an oscoliscope (you can make a one with arduino), 1.3" ST7789 and Nokia 5110 lcds, breadboard compatible flat cables, and a ywrobot arduino power supply (dont try to power it from USB),and an Atmega328p (none of them are in the set)
My fingers are too fat. The hemostats grip wires and such very well and reach into small confined places. I also use them while soldering for the same reasons.
I have never seen offered an Arduino starter kit that I would recommend! They seem to contain so many items that are not very useful, or poor quality, and are missing so many items that are useful.
The most obvious example of an item that is not useful is an Uno. Uno could be useful if the kit also contained several shields, but normally they do not contain shields. Often they also contain a breadboard. Uno and breadboards are a poor combination. A (classic) Nano and a larger breadboard would probably be no more expensive and make a far more useful combination.
Many kits contain other modules, for example sensors, which are not breadboard compatible, and require flying leads to attach them to the breadboard or to an Uno. These flying leads are notoriously unreliable and cause a significant proportion of problems that beginners seek help on the forum with, believing their components are faulty or their code has an error, not realising that the true reason is something so basic.
That's 'cos you don't have a soldering iron! You would soon find it indispensable.
I you don't have a power supply what will you use? PP3 batteries give people no end of trouble, they can't supply enough current especially when you start connecting peripherals. USB wall-warts are OK but only give you 5V. A PSU solves many problems at a stroke at least in development.
Ok. You won't find these in any Arduino starter kit, I think, and they won't be compatible with the breadboards you do get in starter kits, but I have a favourite type/brand of breadboard. They are good quality, modular and highly configurable, and unlike any other breadboard on the market, have rows of 6 connected holes, instead of the usual 5 holes. This may not seem like an important difference, but it can make a big difference when using modules which plug in to the breadboard and are quite wide, such as Arduino compatible boards based on esp8266.
