Hallo joan. Thanks for the reply. Where can i find (or can you help me) on a example in C for blinking a Led? Greatings, Jack To blink a LED you need an access to the GPIO functionality. You'll need a library to do that easily. Take a look here: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=33&...

I too raise a +1 for tapatalk. I think it's a lot handy than a browser.

You've another advantage too, you don't have to power up the arduino separately.

Just a little to add: You'll only need an arduino if you're using an analog sensor, but if it uses SPI or I2C interface then you may connect them directly to the RPi through a level shifter if your sensors operate at 5v.

To get reading from sensors it is somehow good and easy to use an arduino if you don't have an RPi extension like the Gertboard etc. You may connect the arduino directly to the RPi through USB, otherwise you can connect the arduino Rx Tx directly to Rx Tx of RPi through a level converter.

But I don't understand why I can not connect to the internet through usb0 while the eth0 is connected. Can you point the issue out of it? Or is it unlikely a ubuntu side problem? I think there should not be any conflict between 192.168.* IP (usb0) and 172.16.* (eth0) IP addresses. There will not be...

Thank you everybody for your very early and helpful replies, your replies not only fixed the issue alone, also inspired me a bit to do some wikipedia on networking basics. The IP address that I assigned earlier without thinking that much, i.e. RPi: address 112.168.1.5 netmask 255.255.255.0 gateway 1...

1) what is the ip info of your internet access device -No internet access device/router etc, RPi is directly connected to PC ethernet port. 2) what is the ip info of your PC static address 112.168.1.254 netmask 255.255.255.0 gateway 112.168.1.5 3) what is the ip info of your RPi static address 112....

You have a gateway of 192.168.1.254. Is that the IP address of your PC? I've just changed the RPi side eth0 config to the following as Ubuntu was assigning an IP 192.xx.xx.xxx to the connected tethered android device. So, now my RPi eth0 config reads address 112.168.1.5 netmask 255.255.255.0 gatewa...

I'm struggling for a few days to connect my two-week-old RPi to my PC for SSH connection. I've no router, so I've connected the RPi directly to my PC Ethernet port through an usual ethernet cable, no crossover/patch cable. The RPi user guide says that the RPi is clever enough to detect direct connec...
