Arduino Leonardo Android PIN Brute Force

**The code is now up on my blog, tweak it play with it whatever. Just Have fun! http://blog.infosecsee.com ** This is a proof of concept using a Galaxy S3 an OTG cable and the Arduino Leonardo to brute force the PIN. For Demo purposes the PIN was 1023 and the brute force started at 1013. Because of the delay built in to stop brute force attacks you can only enter 5 attempts and then you must wait 30 seconds before trying again.
