In-Depth Information
CryptoCape LED is lit. Each time you press a key, the LED will momentarily flash. Once
all five characters are collected, the LED will turn off.
To connect the keypad to the CryptoCape, you first need to solder 0.1" male pins to the
keypad. Also, you'll need to solder the 0.1" male header pins to the CryptoCape ATmega-
328p pads. Once the pins are installed, now you need to connect a jumper wire from the
keypad to the CryptoCape. Note that the keypad has nine pins but only seven are used.
Consider the first pin, closest to the
*
character as
pin 0
. Connect the jumpers per the fol-
