Re: python script at startup

the other scripts loaded before that are quite similar and they give me no trouble at all... Does the behaviour change if you change the startup order? Is it just that the latest script is 'Too much?' well i m not sure... but i think you're right i tried once to change the order once and maybe the ...

Re: python script at startup

If "analitico.py" depends on "something" (eg. a sensor, network or alike) which is not available when rc.local is loaded or if the script fills up a std[out|err] pipe buffer, this would cause the script to enter a deadlock and this might be hard to debug. The first thing you should do is to modify ...

Re: how to trigger raspi by the doorbell

I would want to use a relay for the trigger input, rather than a diode, capacitor, and voltage divider. Remember that the voltage applied to the GPIO MUST NOT exceed 3V3 or go negative, if it does your Pi may be damaged. this is what i meant: i will try to send a signal with 2.5/3 V to the gpio (us...

maybe it would be more easy if i find some kind of really flat contact switch to put beneath the bell button

So i want to share with you my next project, which i thought i'd make with a microcontroller but, at the moment, i'm much more oriented to a raspberry... so, i hope you can help me to make the right choices. the...

Re: raspberry pi 3 and power led

Yes, it's a power issue. I had this exact problem, except the device drew enough power to reboot the Pi. You can try a bigger (more amperage) power supply, or power the fan with a separate device altogether. except the red led issue assuming i am not plugging any other device to the usb ports... wh...

hi i've made a script to control a fan on the case of my Raspberry Pi 3 model B. when temperature goes over 46.C the fan turns ON... but unfortunately at the same time the Red Power led of the device turns off as well and i don't think it's a good thing at all. i am controlling the fan through a MOS...
