AVR Security Keypad Lock

admin — Thu, 09 Feb 2012 04:20:37 +0000

The Security Keypad Lock Project is a basic access control system based on ATtiny2313. It can be modified to protect just about anything. The “Code Lock” ability will allow the rightful user to deploy the platform to any property that requires simple password-protection.The “AVR” RISC microcontroller used ensures low costs. Possible applications may include: [...]

Generic Finite State Machine Interpreter

admin — Tue, 07 Feb 2012 23:12:34 +0000

A Finite State Machine (FSM) is a versatile mechanism to implement sequential digital circuits. This project implements any desired FSM using the Renesas microcontroller instead of flip-flops and logic gates. The system has a PC based GUI interface where the user can represent the required FSM using a simple State Transition table or a State [...]
