  • This project will allow you to set a breakpoint in your sketch and step through it
  • Proper wiring to each device is supported and expected in some cases
  • Actual Arduino libraries such as Keypad.cpp are used wherever possible.

Help with projects I can help with projects

I sell on Tindie

I have recently discovered TDD which dictates that
all code changes be preceded by a test case enhancement. While I don't have that many test-cases, I do have a suite of
projects which are loaded and tested before every release.

Design Notes

  • SimUtilities Class
    Contains utilities to list all connections and set a value on the connection
  • Pull-up Resistor
    • pinMode (pinNumber,INPUT);
    • digitalWrite (pinNumber,1); // Set pull-up resistor
    • Will have constValue.value = 1, and constValue.resistance = 20000
