  Pausing this.
  Switching over to Propeller learn C Simple lesson 2.

  Dear microcontrolorusor,
  
  Please spell Propeller correctly. Thanks.

  There. It is corrected.
  
  My apologies for any inconvenience that might have caused you.
  
  Probably next is DEBUG experiment.

  I'm still a fan of those BS1 Project Boards. I should have hoarded them all at $29!
  
  @microcontrolleruser: Glad to hear you're all sorted out. I just use LEDs directly, those integral 220 ohm resistors are all you need to limit current to ~15 mA (red) or less for other colors (which have higher forward voltages).
  
  Code for flashing is super simple, just TOGGLE.
  
  do
  toggle 5
  pause 250
  loop
  
  My BS1 P-board robot:

  Erco
  

  do
  toggle 5
  pause 250
  loop
  

  
  Will run that before I take circuit off board.
  
  'integral 220 ohm resistors'
  
  Good info.
  
  Thanks!

  BTW, I have some SX hardware and an SX key if you are interested. Never even fired 'em up.

  Erco
  
  Thank you!
  
  PM'd you.
  
  Been busy with work related stuff.
  
  We'll fit in some 'Parallax' time this weekend.
  
  It's kind of like an addiction isn't it?

  Possible Project
  
  Programs to test 4000 Series CMOS logic gate IC's for 'true'.

  Send signals instead of button circuits I've seen for doing this.
  
  Will that work?

  If by 'true', you mean functional, the answer is yes. For extra credit, you can even figure out what IC (AND/OR/XOR) it is.

  Have you looked at these BASIC Stamp Tutorials for examples of how to program the BASIC Stamp?
  
  learn.parallax.com/basic-stamp-tutorials
  
  The "What's in a Microcontroller" Text has examples of how to Blink an LED and more:
  https://parallax.com/downloads/whats-microcontroller-text
  
  Also, if you need help with understanding Electronics, then you might what to have a look at the "Make: Electronics: Learning Through Discovery" book.
  https://amazon.com/Make-Electronics-Learning-Through-Discovery/dp/1680450263/ref=pd_bxgy_14_img_2?_encoding=UTF8&psc=1&refRID=SR392RDTJF0WS3YKX9P1

  Okay.
  
  What I meant was this.
  
  I didn't really look at the push button examples (no microcontroller) to see what voltage they were using.
  
  Just wanted to make sure these CMOS 4000 Series will work with 5v.
  
  Have some in Radio Shack Electronics Lab but don't know what voltage the experiments are at.
  
  Guess I could look in that manual huh?

  The links i posted were for basic knowledge since you seen to have many questions regarding these subjects.
  
  However, you might have a look-see at this Nuts and Volts article:
  nutsvolts.com/magazine/article/understanding_digital_logic_ics_part_4
  
  What is listed there, they may handle 3-12 volts or perhaps 3-15volts
  
  This seems to have some good info.

  Thanks.
  
  Another project.
  
  Our trusty Parallax stepper motor.
  
  Thinking to plug the leads into breadboard and stare at it and see what develops.
  
  Is Stamp 1 up to that or will we run into an 'Oh No!'?

  Did you look at the Application Note I posted?

  Mike
  
  Are you saying there is a Stepper motor section in it?
  
  I have Stamp 1 App notes as a desktop icon already.
  
  EDIT Okay. It's chapter 6.
  
  Serial Stepper Control routine.

  Found the catch.
  
  App notes has schematic that includes a ULN 2003 IC.
  
  We came around to just using a ready made board for this. But that was with different microcontroller.
  
  http://www.futurlec.com/Mini_SMCC.shtml
  
  Different approach but gets it done.
  
  Will look and see if we already have a ULN 2003 IC or see about ordering one.
  
  Strong point there is App Notes source code will work with it.

  Yep.
  
  https://www.parallax.com/product/500-00005
  
  Pretty sure we ordered one from Parallax.
  
  Hey! There on sale! We paid full price. $1.50!
