What is the advantage/disadvantage of using external pull up resistor other than the internal one?

@TheBoredRobotLLC

2 ай бұрын

One advantage of an external one is if you wanted to use a resistor with a different resistance value than the internal one.

@@TheBoredRobotLLC but why does that matter? Isnt the point of using pull up resistor is so that ur button is not in floating state? So the value of resistor doesn't matter anyway as long as it is high enough to be stable

@@rafiihsanalfathin9479 Yes that is true, but by variable resistance, I was referring to applications that you may want to control current draw.

I found your example to be slightly confusing, and too specific for the title of the video. I re-numbered the pins to reduce confusion with the button numbers, and eliminated the buttons altogether because the video is about Input/Input Pullups, and can be demonstrated more simply without the use of buttons. Another video about debouncing could follow up. It came out nicely, is well commented and runs well. I would like to offer it to you (and everybody else) as a gift in recognition of the work you did to help us. But I don't know how to send you a sketch. can you give me an upload link ?

Thanks for the video! How come it has to be a 10k resistor? Wouldn't a jumper cable also do the same thing (pull pin 3 to 5v)? I am still learning about basic electronic concepts so sorry if it's a bad question lol

@TheBoredRobotLLC

3 жыл бұрын

It doesn't have to be a 10k resistor. A different resistor will work in this example. However, you need to have a resistor, because without it, you're actually creating a short circuit.

@@TheBoredRobotLLC Ah, ok. Thank you!

would you use a input-pullup if you have a design and want to make it smaller (not enough room or breadboard)?

@TheBoredRobotLLC

2 жыл бұрын

Yes, that could be a use for this. I often use input_pullup when I'm using encoders.

does that mean: INPUT_PULLUP just supply the pin with +5V with a resistor, and INPUT is pin voltage is ground?

@TheBoredRobotLLC

Жыл бұрын

INPUT_PULLUP connects an internal resistor from the digital pin to 5V. Using the INPUT command just means that the resistor is not connected.

Thanks!!!!!

0:57 is it just me or is pin 3 not connected to that resistor?

The camera isn't exactly right over the top, so the view might looked a bit skewed. It wouldn't have worked if they weren't connected. If you view in full screen on a monitor, you might be able to see that the resistor is connected to row 17, column b on the breadboard. The jumper to pin 3 is connected to row 17, column c on the breadboard.

awesome! I like the way how you explain it....

very good explanation, but you put the pull-up resistor in the wrong hole

I'm not so sure it's in the wrong location. I do believe it's connected to the 5V rail and one end of the button. Maybe, the camera angle is making things difficult to see? If I am incorrect in any of this, I do welcome any corrections.
