With the recent surge in Omicron cases, shipping may be slower than stated times. We are working to build, ship and respond to everything as quickly as possible. Please see all COVID-19 updates here. Thank you for your continued support.

  • They're designed to run continuously.

  • So could we use a lower voltage and get a lower temperature out of it? This seems like a great solution for a soldering iron heating element.

  • With the simple shields like this, I for one would prefer there to be a small section of protoboard available, possible tying to the other pins. That way, this would have a justified use rather than just making the arduino one shield taller.

  • The "solution" I came up with was simply to use the cursor positioning feature to write to the lines I wanted. Since you're writing strings anyway, it's not terribly difficult to do. If you're making a display for a project, just account for what ends up on what line.

    I can't help you if you need upward-scrolling text. You could try to modify the liquidcrystal library to handle it all on the arduino, but that seems like more effort than it's worth.

  • Not sure if this is normal. My LCD, using the liquidcrystal library, wraps to the third line after finishing the first (then it goes to the second, then the fourth), but addressing each line is normal when using setCursor().

  • Yes, it does. A current flow is reduced along the whole path when it has a resistance at any point.

    So, you can easily stick a resistor after an LED for the same result as it would have before said LED.

  • They're also perfect for plugging across the valley of a breadboard.

  • One very important note: Unlike the Blue and Green LEDs listed, these (and the yellows) have a 1.8-2.2v range, not a 3.0-3.4v range. I burned one out, not thinking to check this for all the LEDs. Not a very expensive mistake, mind you, but one worth avoiding.

  • For those who don't like to follow links, the process is simple. You simply pry away the longer tab (quite visible from the second pic) and rotate the switch along the other tab. You should be able to then simply remove the microswitch, giving enough room for the button to fit through holes, and to get off the nut.

  • These LEDs are wonderful, especially at this cost. If you're looking for fairly large, bright LEDs for a control panel or something similar, look no further.

    I guess the viewing angle refers to the area of the LED that blinds you, because you can easily distinguish lit LEDs from non-lit at over a 180 degree angle. They are really, really bright.

No public wish lists :(
