With so many different parts available, it can be hard to figure out which component to use. Taking a look at what others regularly use might make this process easier.

Note that links may or may not be to the best sourceLook around, add a link if you find a better one. Do not delete a link, unless product is gone for good.
 
 
So many parts, so many variations, which to pick.  Why not try to see what is popular:

If you are working from a kit or a published project consider getting extras of the parts.  If you use them once you may use them again.  Also the authors of these things tend to know and pick what is popular.  Always think about; it there are parts that are exceptions that you would never use again.

Latest revision as of 18:43, 3 November 2014

With so many different parts available, it can be hard to figure out which component to use. Taking a look at what others regularly use might make this process easier.

Note that links may or may not be to the best source. Look around, add a link if you find a better one. Do not delete a link, unless product is gone for good.

Kits and Projects[edit]

If you're working from a kit or published project consider getting extras of the parts. The authors of these things tend to know, and pick, what's popular. If you use them once you may use them again; there are exceptions, though.

PICs[edit]

Because PICs are mostly digital logic, if you use PICs you will need most of the stuff in the Popular Parts#X=Digital Logic section as well as stuff in this section.

What Comment Specific Part


The PIC
  • 16F877A
  • 18F2553 [1]
  • 18Fxxx
Debugger

I don't recommend wasting time on pure programmers for development purposes. Once you get past the blinking LED stage, you are going to need a debugger.

  • RealICE - Mid to High End PICs
  • ICD2 - Broadest range
  • Pickit2 - Low to Mid range PICs


Proto Board

Some People hate them, but many find them a nice quick way to experiment. I have found a max clock speed of 4 megHz works well. Breadboard

see links


Crystals

I keep 4 megHz and 20 meg Hz on hand. Note that some PICs can do without crystals, but timing is not very accurate. Check your spec. sheet, some PICs may be able to go to 40 meg Hz. Note that a couple of capacitors are needed as well. Ceramic resonators may be used instead.

  • 4 meg Hz
  • 20 meg Hz

Pull Up Resistors

Can be used as pull down as well. I use 10k ohms, often useful for other stuff as well.

10K


Generally Useful Chips

Op Amp Need to condition your inputs? a op amp may be just the thing. See section on op amps.
LED How else can you say hello world? Pretty much anything will do. Do not forget to get a current limiting resistor 220 ohms or anything close. LED also come in arrays and as 7 segment displays for numerical read out.
  • 220 ohms
Push Button Need this for input. I get mine from salvage. Later I will find a source for you.
  • see links
Low Side Switch, Driver Chip When you need more power from an output port this is the way to get more than 10 times a much current, Not very expensive. One chip will drive 2 stepper motors. ULN2803 has 8 inputs and outputs. ULN2803
High Side Switch Driver Chip Like a low side switch, but on the high side. If you are driving "rows and columns" then you need some on the low side some on the high side. The UDN2981 has 8 inputs and outputs. UDN2981
Sensors There are so many, for light photo diodes and transistors, for temperature LM34 and similar see section on Sensors. *whatever
LCD Display Put out full alpha numeric data, several characters. Seems like a better? solution than LED when many characters are required. Probably best used with a controller to keep use reasonably simple. *HD44780 parallel interface

Digital Logic[edit]

If you use any microcontroller, you will probably also need most of the stuff in this section.

What Comment Specific Part


Gates
  • 74HC132 Quad 2-in Schmitt-trigger NAND gate


Counters

  • If you use a microcontroller in your project, the counters inside that microcontroller will probably be all the counters you need.
  • ?


Shift registers

Often used to expand the number of ports.

  • ?
  • 74HC595 -- for more output pins. SIPO eight bit shift register with output latch. Perfect for letting the propeller clock POV display slowly clock in the next value, then LOAD them all at once. Near the bottom of the page describing the "Digital Numeric LED Displays Tachometer (RPMs), Temperature, and Counter" project, David Cook says: "The 595 is a great 8-bit serial chip because data can be shifted in without affecting the existing output. All new data is then switched over at the same time. The 595 can also be daisy chained. In this case, 48 outputs are controlled with only three wires (data, clock, and latch)."
  • 74HC166 -- for more input pins. PISO 8-bit parallel-load shift registers.
  • 74HC165 -- for more input pins. PISO 8-bit parallel-load shift registers.



Voltage Regs Power to the Chips
  • LM7805


Voltage Reg

Easy choice is LM7805. A couple of caps usually go with it. .1 and .01 bypass caps are generally useful.

  • .1 uf
  • .01 uf

decoupling capacitors.

"I can only recall using less than 1uF decoupling cap in one circuit in the last 8 or so years ... 100nF bypass caps [0.1 uF bypass caps] are so 1990s. If someone tells you that should be the standard value, you should be careful about what other bad or outdated advice they may be dispensing." -- one post in the PICList Thread (EE) "1.0 uF Decoupling Cap - A Must?" by Olin

  • 1uF through-hole caps for solderless breadboard
  • 1uF 0805 ceramic caps for dead bug style prototyping and custom PCBs
