Hi all
There is already one 100 uF condensator attached between ground and 5V where it enters, I hope this is enough for the decoupling or am I misunderstanding this? (sorry pretty new to electronics!)
The extra LED might be a good idea but will take some time to implement as it's a closed system... I'll check how I can do this! Adding an extra arduino is not feasible at this time.
I didn't use any Strings so no string class afaik but I'm using 3 includes: #include <LedControl.h> (matrix), #include <Wire.h> and #include <DS1307.h> (time).
Posting code would be fine for me but than it doesn't feel like solving the issue any more but just (ab)using you guys
