help! photocell needs to trigger mp3

-

i'm brand new arduino, , i've been digging own grave making more complex needs be-

i know how wire board, i'm clueless how code it.  basically, need make when photocell detects light, triggers mp3 on computer or through itunes (i have mac).  if kindly steer me towards code work this, incredibly grateful.


thank much!

you need software on mac can read serial port , start mp3 file playing.
arduino nows nothing mac's / pc's / folders / files , that.

it's easy set photoresistor voltage divider , use analog read on arduino board "light level" reading. send on seral line mac, theres no way arduino board can start playing mp3 file on mac. program on mac must listening on serial port arduino board sends , take action.

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
