hi,

i'm new using raspberry pi , hoping me build circuit activate solenoid.

using cobbler breakout kit , have figured out how set 1 of gpio pins high know not enough power solenoid directly ( http://www.aerco.co.uk/images/sub_sub_c ... ries68.pdf)

have 12v power supply can hook solenoid wondering how use 3.3v output of gpio pin activate it.

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
