I’ve just realised that the campaign I’ve been\u00a0featuring on the\u00a0blog for the last few weeks is almost at an end.<\/em><\/p>\n

\"\"<\/a><\/p>\n

The RasPiO GPIO Ruler<\/a> is a great little reference guide to the RPi.GPIO Python library\u00a0that (almost) everyone uses to interact with the GPIO pins on the Raspberry Pi. Since Alex sent\u00a0me one of the prototypes, I’ve found myself forgetting how to use the library more times than I care to admit and I found myself thinking “Oh, I wish I had a quick refer… Oh, I do!” and into my bag I delved once more. It’s now, unaccountably, become one of the ‘essential’ pieces of kit I carry in my Pi bag.<\/p>\n

It is available on Kickstarter until tomorrow morning<\/a>!<\/p>\n

As you can see from the pictures, it solves multiple purposes. It can act as a slip-over reference for the GPIO pins themselves with both functions labelled depending on which way up you have it; it tells you all the different functions of\u00a0RPi.GPIO; it’s a ruler (I’ve even used it as a ruler!); it has\u00a0a handy URL to go to for GPIO tutorials.<\/p>\n

I really can’t recommend it enough. It’s only \u00a34 plus (very reasonable) shipping.\u00a0Delivered, it’s\u00a0a fiver in total for the UK. Alex has had a good level of success in his campaign <\/a>so far, but I’d love to see him get to 1,000 backers before it finishes just after 8.20am tomorrow morning.<\/p>\n

So, if you haven’t pledged yet, or if you want to order more of them, head over\u00a0to Kickstarter<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
