The Arduino IDE has built-in functions for keyboard and mice emulation. If you wish to use a different development board than the Pro Trinket, it is suggested you consider the Arduino Micro, Leonardo, or Due. TrinketKeyboard.typeChar((char)random(33, 122)) // type out a random character (valid ASCII) While (millis() < (time_stamp + (secs_to_wait * 1000))) // wait the random amount of time While (millis() // include the Adafruit library Unsigned long secs_to_wait = random(6, 60) // wait 6 to 60 seconds between keys
