How to set Clock frequency for Arduino UNO
Nov 21, 2014 · Say your code was talking at 4800 - then you adjusted the system speed from 16 MHz to 4 MHz. Your code would need to change the serial speed to 4800 x 4 = 19200 so it would still look like 4800 to external devices. Using external crystal: if using other then 8 MHz or 16 MHz is used, Riva has addressed that already.
