  • Jon,

    Thanks for sharing your slides.

    I am really intrigued by your notion of assemblages of hard and soft technologies.

  • Hi Darren,

    This is very informative as I wanted to increase my understanding of pull-up resistors. The SIK guide was brief in its discussion on this topic. I intially thought that the pin only contained 2 states but after going through the article, it appears to be 3 states: LOW, HIGH, and floating. The floating state was a surprise as I didn't realize that the pin can go randomly between LOW and HIGH. This tells me that if I'm using a pin with a pull-up resistor, then I should clearly define the pin state.

    Thanks for posting this link,
