8 SQUARE
This is the 8 SQUARE.
Arduino compatible matrix LED badge.
I bought it at Maker Faire Shenzhen 2014.
Make single matrix LED into double matrix LED. So 8x8 into 8x16. wide screen !
Hack the 8 SQUARE !
No need modification of 8 SQUARE. Make a socket adapter of two LED change into one LED.
This is a schematic of the adapter.
Combine each anodes and cathodes. i.e. A1 - K1, A2 - K2, .... K1 - A1, K2 - A2, .....
This is actual wiring.
The adapter completion.
Unite with 8 SQUARE.
Sample patterns.
Sample sketch is here. ikkeiplexing_8SQUARE_140529.zip This sketch is NOT battery-saving yet.
Hack the 8 SQUARE 2 !
Use 0.8” small square LED.
Schematic is same as mentioned above. This is actual wiring.
There are interfere crossing pin headers, so use ZIGZAG universal PCB.
The adapter completion.
Unite with 8 SQUARE.
Sample patterns. It’s like the Titchaino that is my original work.
