Only using Arduino Nano and clarkwise touch screen
Maybe it is a little out of surprise, but it is actually very simple of imitating Irene Alder’s IAMSHERLOCKED trick.
All the resource file has are pictures and a String Input Control.
The trick is to make sure using Monospaced font. And limit the String Input Control to 4 bytes only.
The background image contains 4 blank, each for a letter of String Input Control.
Every time a user inputs a password (string), the String Input Control will send it back to Arduino Nano via UART. If the string is “SHER”, Arduino Nano will send an audio playing command (the sexy noise from Irene) and then switch to the correct GUI.
This is just a demo, but it shows how easy to create a good-looking password protection system.
