microTone Module is analog interface to connect microcontrollers or digital logic systems with PCs. This interface use PC sound card’s audio output terminal to send commands to external hardware systems. microTone Module is an open source project and all its software source codes and hardware designs are available to download at sourceforge.net/p/microtone . All the compiled software and source codes of this project are distributed under the terms of GNU Lesser General Public License . Hardware design and other documents are distributed under the terms of Creative Commons Attribution-ShareAlike 3.0 Unported License . Software library of microTone Module is a Win32 DLL and it can use with any programming language which allows interface with dynamic link libraries (e.g: C++ , C# , Python , Java , Delphi , Visual Basic , etc.) Some wrappers for this DLL are already implemented and available to download at microTone Module sourceforge.net code repository. And also if you implement or...

LEDShoot is a simple electronic shooting game which we developed in a year end vacation period. This is a single player electronic game with following game play logic: There are two fighting groups are exists in this game world. RED group is an enemy group and GREEN s are friendly parties. Player’s job is to shoot the RED group(s) when they appear on the stage. Player gets limited time to shoot and misfires are treated as negative points. When player get 100 points game get end with winning message. This electronic game system is mainly based on ATmega32 MCU and firmware is developed using GCC C (with Atmel Studio 6.0). This system is design to work with 5V - 1.5A power supply unit. We developed this system as a hobby project and we construct it on a couple of breadboards, at the moment we don’t have any PCB design for this project. When assembling the circuit make sure to use some heavy-duty push button for ( SL2 ) control key. For ( SL1 ) use 8 Ω - 1W (60mm) sp...
