What do I need to send and recieve data

-

i'm purchase bunch of stuff need know additional stuff need get. main goal send data arduino c# , receive data arduino in same c# program. if buy arduino mega, other components need? have looked on internet haven't found clear definitive answer. don't know if need serial usb adapter or if arduino somehow tells computer usb port can used com port.

thanks

you don't require additional arduino board. part of arduino software installation installing ftdi usb serial comm driver. once loaded pc system show new additional comm channel (mine shows com4) anytime arduino plugged pc.

pc application programming language can talk pc comm ports have path send , receive serial data attached arduino board.

hello ! wrote today article on blog cpu load monitoring (using gpio , leds) on raspberry's. simple (written in little shell script), think can useful (for people want learn leds stuff on r. pi) there 5 leds turning on , off regarding cpu load: - cpu < 20%: 1 led - cpu < 40%: 2 leds - cpu < 60%: 3 leds - cpu < 80%: 4 leds - cpu < 90%: 5/5 leds - cpu >= 90%: 5 leds flashing here article: written in french, can watch youtube video , download code @ bottom of article. http://www.chteuchteu.com/2012/10/26/ra ... e-au-gpio/ if find errors in code, can post comment on article. ! up code enhancements ? raspberrypi
