I want to build a panic button so when the button is pressed it sends a command to the pc (probably vb that will then set of an alert) im not sure how I can send it from the Arduino. could I possibly write com data? Really out of my depth !
could I possibly write com data?
Of course.
Serial.print("Panic!");
check out Arduino Playground - InterfacingWithSoftware. this page has got excellent links to interface with stuff like VB, Python, Processing, etc etc.
I wrote a blog post on basic Arduino - Processing communication which you might find useful if you are new to serial communication using Arduino and stuff like that. Here is the link: The BluBot: Interfacing Arduino from Processing
ah thanks heaps to you both. WIll check these out in abit
