Digital voltmeter – Arduino and PC (Visual C++) comunication via serial port

Today I will show how to make digital bridge between Arduino and PC: control analog – digital converter and send measured data to PC. Windows application will be created using Visual C++ 2008 Express.

Voltmeter demo software is very simple, and here is a lot room for improvement, but I just wanted to show basics how to control com port and execute data exchange between PC and Arduino.

LED resistor calculator for windows v1.0 (download)

This is the very first and I hope not the last post of this blog.  With this event I want to share with you LED calculator. It is also my first project with Visual C++ Expression 2008, this  software development environment is free for students.

Calculator is capable of finding suitable standard E12 (10%) resistor value and power for one LED designs.  There also some tips for user to find LED forward voltage:

Calculator works on Windows XP, Vista, 7, but you have to install Microsoft .NET Framework 3.5
