I’m looking at purchasing a Evil Mad Scientist Clock and was wondering if there are spare inputs that could be used by external source triggering.
I’m not actually looking to use this as a clock, but more for a remote display. If it was not possible to have an extra input, would I just not solder in the function buttons to use as external wires in their place?
If that doesn’t work, I’m thinking of using a 2nd Arduino to just feed serial data to the clock, but that seems redundant.
I suspect that you’re asking about the Alpha Clock Five, not the Bulbdial. ;)
There’s no obligation whatsoever to use it as a clock. You can feed serial data to the clock using a USB-TTL cable, or another Arduino, or use the available spare I/O pins any way that you like. The current version of Alpha Clock Five has 9 (if i counted correctly) spare I/O pins that can be used as inputs, not counting the two pins that go to the second serial port.
I hope that this answers your question; if not, please let me know how I can help. :D
