Re: infrared beam

Hi, I am slightly out of my depth here but I figured I have come to the best place for advice. I am interested in using an infrared beam to detect whether or not a person puts their hand in a box. I understand that, in principle, this is possible but I have no idea how to get started. I was wonderi...

Re: rpi cant ping outside of subnet unless www

Hi

Do you want/need a separate sub-net?

Could you perhaps make the pi 192.168.0.191 and its default gateway 192.168.0.1?

Re: Progress OpenSuSE

Thank you.

I will follow the links and try and learn.

Could the Jeos version be adjusted to create a 180 MB boot partition?

Re: Control of Linear Actuators

Hi 3 linear actuators. Reminds me of a stretcher, a Bull and a cockpit. Self levelling stretcher/beds in the rear of ambulances, those rodeo bulls and flight simulators all use this king of thing. So maybe out there is some information on howto, the self leveller used IMO equipment and the rodeo bul...

Re: Raspberry PI for heating system automation

Hi

If you could post a bit more about the boiler controller and it's wiring, then maybe some help could be given.

Re: Progress OpenSuSE

Hi

Well I got a JeOS to boot. No GUI available.

So if I want to make/create the equivalent of JeOS where is it done?

Back into NOOBD for now.

Progress OpenSuSE

Hi

I would like to be able help to progress OpenSuSE for the Pi.

Starting from the beginning, which means me being very pedantic and asking stupid questions.

So...

Where and how can it be found and ported to the Pi.

Re: GPIO pins have 0v

[quote="Burngate"]Things are getting muddled, so...pin is 3v3, third pin down on the right is ground, so between those two should be 3.3v


Hi

Muddled enough to consider a re-install of NOOBS then when booted measure voltages before any other software is installed or scripts run.

Re: First try: only get NOOB v.1.3.2 on screen

HI

Hmm

I would try the TAB key for navigation and try 'install' by pressing 'Return'.

Re: GPIO pins have 0v

Hi Well to hazard a guess... You posted some code import RPi.GPIO as GPIO import time GPIO.cleanup() GPIO.setmode(GPIO.BOARD) GPIO.setup(3, GPIO.OUT) while True: GPIO.output(3, GPIO.HIGH) time.sleep(5) GPIO.output(3, GPIO.LOW) time.sleep(5) in which, as somebody that don't do python cept once, sees ...

Re: Understanding the code

What does the GPIO.cleanup() actually do? See the author's documentation, here - http://sourceforge.net/p/raspberry-gpio-python/wiki/BasicUsage/ (scroll down to about two-thirds through the document, section headed 'Cleanup'.) Thank you. This means that if I have an LED that that is Bi-Colour, Desc...

Hi

Can you give me the reasoning please. Elsewhere I have seen different values specified.

Is it the voltage?
The current?
Or if the led fails?

Re: GPIO pins have 0v

Hi The thing below worked for me after a lot of struggling. ############################################################ I connected 2 LED's, an Orange to pins 22 and 25, then a Green to pins 6 and 15. This meant that when I specified output 22 I had both options covered. /home/pi/Desktop/ledtst.py ...

Re: Led control for absolute beginner

Hi Thank you both. I read another post (GPIO Pins not working) and noted a difference in the python I had copied. So I changed the code and method. I got a result. I then managed to modify the code to get a different result. I connected 2 LED's, an Orange to pins 22 and 25, then a Green to pins 6 an...

Led control for absolute beginner

Hi I am trying to control an LED on my Pi, and I have seen lots of posts about how. None work for me, my preferred method of learning is more visual than abstract. So I know that Pin 1 has 3v3 on and Pin 2 5v0, along with a GND Pin 25. How can I make one of the GPIO pins active to illuminate me and ...
