Re: Flying Pi

Not sure if this it too late to help you but for the distances you are talking why not just run a CAT5 cable up the Kite line? Not sure if it would add too much weight though!

Re: Home button

This is how you can use a button for input on the PI for this kind of thing - http://www.pickupapi.com/blogs/pitronics/13038953-pitronics-part-8-buttons Don't be tempted to use a if or while loop to check the pins state, it will massively effect the performance of the pi. I'm not sure how to minimiz...

Re: Help for beginner

I've adjusted your code slightly to make it work b=raw_input('enter first number to add') b c=raw_input('enter second number to add') c a= int(b) + int(c) print a Your not using a function so you don't need the returns, also you need to parse the input to number if you want to add them as numbers ra...

Re: Problem in Internet Connection through Ethernet Cable

Can you open up a LXTerminal Window and let us know what the output of running the following command gives?

Code: Select all

ifconfig
Do you normally have to set an IP address for your windows machine or does it pick one up automatically?

Re: how do I execute my code file after saving it in RPI?

You would be better to use a python event rather than checking for the value of a pin every few seconds if you want to detect button input For Example def DoSomething(channel): Do Something sleep(0.25) GPIO.add_event_detect(11, GPIO.FALLING, callback=DoSomething, bouncetime=300) Just replace the Do ...

Re: Rover and Raspberry PI

Not sure about your other requirements however for the motor you will probably want to look at using some kind of H-Bridge, look at a L298N board, its got 2 Hbridges so will allow you to controll the direction of 2 different motors, it will also allow you to put up to 12V into them.

Re: Raspberry pi robot

You might find it easier to stick a WiFi dongle on the Pi and control it through a web browser than using actual 'radio control'. With regards to the H-Bridge its easy enough to do, as the poster above said you really only need to connect 2 pins to the Pi, however for more accurate movement if you n...
