  • Open Collector outputs can be tricky to understand. In this video, Chris explains enough of the details to get you "over the hump" so that you can work with them on the PICO and other electronic devices.

    Fantastic explanation of how the open collector output work and why there is no harm on having the sensor running with more than 3.3V. Thank you Chris!

    Very informative video. By the way, I'm Vietnamese, and hearing "Chào buổi sáng" in an electronic video was quite unexpected, which pleasantly surprised me. Thank you!

      Hello buiminhtue7539,
      I am fortunate that in my profession, I meet a lot of different people. Out of respect I try to learn how to say something in their language. When I was much younger and could remember things, I learned a lot of phrases in many languages.
      For me, it is a fun way to connect with people on a personal level.
      Now that I am older, I try my best to learn how to say "Good Morning" in the person's native language. If I can pronounce the phrase, I can usually remember it, at least for a while.
      If I am working with a group that all speak English as their first language, I try to share with them how to say good morning in another language. With the videos, I figure I will touch some of the people and hopefully connect with them such as with you.
      I am glad you were pleasantly surprised!!!!
      Cheers!
      Chris

    Thank you for an excellent explanation of the use of such a ubiquitous circuit.

    Another benefit might be that multiple switches (fysical or transistor) could pull the same input pin to ground. That might come in handy for some kind of interrupt-system, where multiple devices can interrupt the CPU when they need attention (think keyboard, disk drive, UART). The CPU must do some discovery to see which device pulled the interrupt ping low ;-)

    How or why does adding the 10k resistor add 0.05mA of current?

      HI Brandon-zj4hr,
      Can you help me with a little context or something. Are you referring to the fritzing diagrams?
      Cheers!

    I think both grounds should be connected together (common ground)

    • @MakingStuffwithChrisDeHut
      @MakingStuffwithChrisDeHut  Рік тому

      When needed / possible, yes. When the "Ground" is at the same potential, it is not need which is often the case with simple battery powered devices.
      Cheers!
