LED Matrix using an AVR ATTINY2313 and 74LS374
This is a little circuit to drive a 5x7 jumbo LED matrix module that I picked up at a local hamfest. All it takes is a ATTINY2313 and a 74LS373 octal latch to create a row/column mux to access the individual Leds in the module. Attached is the schematic. the 6pin ISP programmer is not shown, this is a given , if you're using one of the available programmers, such as the AVRISP mkII from Atmel. I will post a pic of the module shortly with the pins labled.
NOTE: Atmel released a newer version of this microcontroller, it's now the ATTINY2313A
I may have some old network routers and switches that you are welcome to take if you come get them. I am in the Southside.
