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.
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
