Hi...I'm new here. I have an Uno and so far I just played around with sequencing leds.
What I want to try and do is have 2 or three audio files that play at random order when an input is selected..... then when another input is selected I want it to play 3 other random order files....then when a 3rd input is selected....3 more at random. Oh... I need to drive thru a speaker at reasonable volume. Oh and...I also need an 4 input to drive a relay with a timing circuit in the 2 minute range.
Is all this possible with a single Uno? What would be my best shield option for the audio? I could use mp3's or wav's or whatever is best. Will I need an addition small amp?
Any ideas welcome and appreciated....
Thank you for letting into your forum.....gj
