Hi guys
simle question here regarding a button.
i am using a button in a project and when its pressed a if and a for loop start.
the button state is being read as high but when i do press it seems to miss it.
i think the code is possible running to fast for it to be read when i press it or something do i need to add a debounce feature or a delay to make it read.
code attached
#include <Wire.h>
#include <Adafruit_MMA8451.h>
#include <Adafruit_Sensor.h>
Adafruit_MMA8451 mma = Adafruit_MMA8451();
