Re: Can't Get LED to light

i can't work out how to attach an image of my circuit. Further down the page from your text entry box you will find an "Add files" button. However, the file size allowance is very small so you would either have to pre-process your image file to make it small enough (fewer pixels, low JPEG quality) ...

See post 3, it's a verbatim quote from the second paragraph in the reference provided - but conveniently there is a link to the item in question a few words later! There seems to be no mystery other than the nomenclature.

Re: Open Source hardware?

What made it not clear is that the infirmation calls it a breakout board instead of an IO board.

Yes, but it is not obvious that those include details of the breakout board.
Correction: maybe it does - look at the IO boards. The "breakout board" is described as Compute Module IO Board V3.

Re: All pins fried, don't know why

"don't know why"!!! You must regard wiring any RPi signal directly (ie without hardware protection) to any assembly powered by a voltage in excess of 3.3V as a risk. Just because people get away with it doesn't mean they will always get away with it. The I/O characteristics of pins (at both ends) ar...

Re: How do I protect my code?

I would suggest using something other than an RPi for the product's intelligence. You might like to look at the Microchip PIC range of micro-controllers, or Arduino - which has much of the same "interfaceability" as the RPi (although not as much computing power - do you really need that much?). In p...

Re: Pin 1 and Pin 2 short circuited

But the board looks good.No any burnt smell or fried components. You don't appear to understand what has happened. Let me spell it out for you in detail: Pin 1 on the GPIO is the 3.3V supply that runs all the electronics of the RPi. Pin 2 is the 5V input voltage that is used to create the 3.3V. By ...

Re: BBC BASIC for iOS

Strange, I think my observations are relevant to posts 2-9 (or are we not allowed to discuss anything other than the first post in a thread?!). You are entirely at liberty to disagree, the idea of a forum is to be able to voice opinions.

Be that as it may, my point is "horses for courses".

Re: Remote GPIO button input

The thing is I don’t believe it’s a hardware issue. The RPI with the MP3’s runs fine on its own if a button is connected and the RPI with the button connected using the script is able to use remote GPIO to access and run those MP3s. It just won’t wait for the press of the button before running and ...

First of all you need to check the switch is wired correctly. See HERE and skim down to the section on Hardware Interfacing.
