An LED dice circuit sculpture defend for the UNO Mini LE

Few gadgets are extra iconic within the maker group than the Arduino Uno board. To have fun the Uno’s historical past and beloved standing, we launched the UNO Mini Restricted Version in late 2021. This little board is a tiny duplicate of the usual Uno, however with a particular black and gold shade scheme. Whereas the UNO Mini LE is collectible, it is usually a completely useful growth board. Hari Wiguna took benefit of that truth to create this LED dice circuit sculpture defend for it.

The UNO Mini LE’s specs are virtually equivalent to the usual Uno Rev3, since they share the identical Microchip ATmega328P microcontroller (simply in a distinct bundle). However the small dimension of the UNO Mini LE signifies that it isn’t appropriate with regular Uno shields. Wiguna’s defend matches on the UNO Mini LE and supplies a flashing circuit sculpture dice of LED goodness.

The dice is 4 LEDs tall, 4 LEDs extensive, and 4 LEDs deep, leading to a complete of 64 LEDs. Wiguna organized these as an array of 4 matrices to maintain the I/O pin depend down and to simplify indexing. The PCB defend was professionally fabricated, however the dice required hand-soldering to create the copper lattice construction that doubles because the circuit for the LEDs. To point out off the dice’s LEDs, Wiguna coded a sketch that features 3D animations.
