For instance, this example blinks 6 LEDs attached to the Arduino by using a for() loop to cycle back and forth through … Web2 mrt. 2024 · And also 16 MHz is the raw clock rate. You have to look to see how many clock cycles the µC takes to execute an instruction. No, it's not that. The loop itself is very fast. The problem is digitalWrite () is very slow as it does things such as mapping the virtual Arduino pin number to a physical port and bit.
