What basic set of radio components should a novice arduinian buy?

Question

Arduino

Of course, I understand that it’s still impossible to avoid periodically running into a radio parts store to stock up on missing components ... But, probably, everyone has some kind of basic set of resistors of their favorite ratings, capacitors, transistors, all useful iron and other good things. Well, that is, some kind of minimum, which should be enough at the prototyping stage. Can you describe your basic set?

Answer 1

Resistors are conveniently dialed on a logarithmic scale:
100, 330, 1kOhm, 3.3kOhm, 10kOhm, 33kOhm, 100kOhm, 330kOhm.
330 and 10 kOhm is better. The first to the LEDs, the second to "pull up" the logic levels.
Of the capacitors, it is worth buying more ceramic ones at 0.1 microfarads.
Electrolytic for 100 ... 1000 uF for the desired voltage with a margin.
PLS, PBS, BLS connectors, solderless breadboards (for prototyping) and mounting textolite (for soldering) and wiring harnesses are useful.
LEDs, of course.
Trimmer resistors and potentiometers, for example, 10 kOhm.
Schottky diodes 1N5819.
Voltage stabilizers 78L05 and 78L33 or similar for 3.3V and 5V.
Operational amplifiers with suitable supply voltage LM358.
From transistors it is worth taking NPN and PNP, for example, BC547 and BC557 for low-power loads (larger NPN) and some IRFxxxx mosfets to control a more powerful load (LED lamps, for example).
Sensors, modules - at your discretion and to your taste.
A multimeter and a laboratory power supply, even the simplest one, are very useful.
