  • pull up vs pull down

    if you had a circuit with a few switches, wouldnt a pull up architecture draw more current than a pull down ?

    if it was going to use a battery, wouldnt you want to choose pull down when possible?? 0 is a pretty low current draw.

  • ok, i will give them a shot.

    i tried the hall effect sensors.

    they worked but the latching is a problem. the reed switches seem like a simpler solution for what I am doing.

  • i have these wired with 5v on 1, signal on 2 (middle), and gnd on 3

    it senses the magnet but the output pin is showing .5 volts I was expecting 5v or at least 3 volts.

    i had the same results with 3 different units. I also tried a 10k resistor across 1 and 3 which didnt help.

    Update::::

    nevermind, had the wrong pinout. 2 is gnd, 3 is signal. working now

    sure would be nice if the basic pinout was shipped with the product.

  • i am making a chess board that will automatically record moves (and eventually store in pgn format) Will this type switch work for that application. I would mount the switch (64 of them, 8 x 8) under the board then, using magnetic chess pieces, the switch would activate when a piece is moved.

    I need something small and low cost. that can fit in the size of a chess square and work through a small piece of wood or cardboard. a $5 switch would make for an expensive project. this looks like it would do the trick if it will work through the chess board. I need to get chess pieces with strong magnets.

    per the other users, non-latching would be better for my project.

  • I think I ruined this trying to solder to the connect points, would like easier way to hook up.

  • where can i get a 3-pin connector to breakout the RX, gnd, 5v for easier access maybe to a screw terminal or female connection
