While the Mega is a large Arduino with plenty of GPIO, its CPU speed is still the same as that found on the UNO and Nano (same Mega family) and so there is no speed advantage to using the Mega. And now I wondered if I did that right. The second If the Arduino was running at a different speed (say 1MHz rather than 16MHz) then the communication wouldn't work, since changing the clock frequency would change the baud rate. Many receivers also have additional outputs for a unique type of serial bus. I tried using the command: void setup() { CLKPR = 0x80; CLKPR = 0x08; Serial. an ADC converter).
