i just made this clock scanner and door opener. it has a servo, 2 leds, a button ,display and a pieco element to "hear" the knocks. controlled by an arduino mega.
theres a record mode, turned on with this switch there (i had no button here)
its just the prototype.. i still need to work on the code because sometimes its doing weird stuff. and another 5V power supply would be nice :D
good job man,this maybe a next genration of the metal keys :))
