| Small toy with a 4*4 LED matrix using an AVR ATmega8 controller and 16 10mm LEDs
Hardware
The matrix is driven in multiplex-mode.
In hardware-version 1.0 the LED-anodes of every row are connected to each other and via a current limiting resistor to a port-pin of the AVR (one row per pin). The cathodes of every column are connected to each other and the collector of a NPN-transistor. All emitters are connected to GND. The transistor’s bases are connected thru current limiting resistors to AVR port-pins (one base/column per pin)
