  • It’d be really great if you could post the circuit diagram. i.e. how the SMD resistors I see on the strip are connected to the LEDs. Otherwise, figuring out what voltage to drive it with will be guesswork. Thanks!

  • I want to make sure I understand the datasheet correctly:
    Each pin can output up to 35mA, but all together the chip can output up to 70mA?

  • If an 8-bit integer is 255, and you increment it, it will rollover and become 0. 8-bit integers can only hold a value from 0 to 255. The condition part of the loop would have to be “x < 255” or lower.

No public wish lists :(
