    Hurrah!

    Fixed all the dodgy LEDs on my TM1638 LED&KEY module, then completed and published the code for my easiTM1638 Arduino library.

    Never encountered so many dim or plain not working LEDs on one small board - I ended up replacing 3 out of 8!

    Enjoy!

    Hoping for a bit of inspiration, or even an explanation...

    I have a #TM1638 LED&KEY module attached to an Arduino. I have no issues with the code.

    I do have issues with a 2 of the LEDs. I can see that they work, but 1 is dim and another is very dim. The board has no current limiting resistors as the LEDs are pulse driven. I can turn them on and off, so I know they work somewhat.

    I could replace the LEDs, but without knowing why they are dim, I think it might not fix the issue.

    As I work on my #Kim1 emulation project rabbit holes, I am having a lot of fun with various LED 7 segment displays, or rather the #Arduino library code for the driver chips!

    I already have a library for a Gotek 3 digit display that uses a #TM1651. I wrote this 6 months ago while in a rabbit hole as I upgraded my Gotek.

    I am adapting it for a 6 digit display that uses a #TM1637, and for an 8 digit display that uses a #TM1638.

    And I am also playing with an 8 digit display that uses a #MAX7219.
