Discussion Overview

The discussion revolves around selecting resistor and capacitor values for home-brew electronics projects, particularly those involving LEDs and PIC microcontrollers. Participants share their experiences and suggestions regarding component values and purchasing strategies.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant requests suggestions for commonly used resistor and capacitor values for bulk purchasing in home projects.
  • Another participant argues that there is no single "most used" value and suggests determining specific needs before purchasing.
  • A third participant mentions standard value series (E12/E24) and recommends looking into grab bags or kits for component assortment.
  • One participant shares personal preferences, starting with 10K ohm resistors and 0.1 microfarad capacitors, and notes typical ranges for LED current limiters and pull-up resistors for PIC inputs.
  • There is a suggestion that capacitors are primarily used for bypassing power pins unless involved in analog filtering.

Areas of Agreement / Disagreement

Participants express differing views on what constitutes "bulk" purchasing and the necessity of specific component values. There is no consensus on a definitive set of resistor and capacitor values to use.

Contextual Notes

Participants reference various standards and purchasing options, but there are no detailed specifications or calculations provided for the suggested values. The discussion lacks a clear resolution on the best approach to component selection.

Who May Find This Useful

Individuals involved in home electronics projects, particularly those working with LEDs and microcontrollers, may find the suggestions and discussions relevant.

Anyone could suggest which resistor and capacitor value that used most in home-brew project? Those project basically deal with LED and PIC. I want to buy them in bulk, but I do not know how to assort them. I wish to buy like 50 resistors and 50 capacitors. Looking forward for your help.:)

50 resistors and 50 caps is not "buying in bulk" and there is no particular value that is "most used." You should figure out what values you need first.
 
Hey Prescott2006, There aren't just a few values used however there are standards of values such as E12/E24. You may find this helpful in deciding what components to purchase. Also, 50 caps and resistors are not bulk, when you talk 50,000 that is bulk. Perhaps you would be interested in some Grab bags or kits such as those on Sparkfun.com or http://www.futurlec.com/ValuePacks.shtml, Jameco also has grab bags as well.

For more reading on Preferred Values check out Wikipedia - http://en.wikipedia.org/wiki/Preferred_number

and here is a preferred value calculator: http://www.random-science-tools.com/electronics/preferred_values.html

Hope this is helpful and best of luck on your next project! :)
 
I always start with 10Kohm and .1microfarad and work from there. LED current limiters might usually be in the 100-470ohm range. Pull up resistors for PIC inputs could run from 10-100Kohm.

Certainly, find a grab-bag-assortment of resistors. But, unless you are making analog filters, the only use for capacitors is bypassing power pins, so .1uf might just do you.
