I am totally new to the topic and purchased an Arduino micro for my project.
I have a credit card reader that sends out a pulse every time a transaction is made, this pulse should start a photobooth running on a win7 laptop. The photobooth software can be started by pressing a letter so I thought about using the "KeyboardWrite" code?
My first question is where to connect my pulse cable to the Arduino?
I am totally lost and have no programmingskills whatsoever, I hope someone can point me in the right direction...
