Having just bought EL Sequencer I was pleasantly surprized to find it equipped with a ATmega328 and not a ATmega168 as specified. It would be nice if the documentation was updated as schematic shows 168. But there are more serious problems with the documentation.
Schematic shows the eight TRIACs on pins PD2…PD7 and PB0…PB1. Sample code uses PC0…5 and PB0…PB1. Out of box the EL Sequencer is not working.
Something is really mismatched! 
Can you (i.e. Sparkfun) fix and post with accurate schematics and working sample code please!!!
