You may remember this time last year I KickStarted a 6-inch ruler with the most important RPi.GPIO code on it. I’ve been using it myself an awful lot in the last year when coding. So it won’t surprise you to learn that I’m now doing another one for GPIO Zero. Since GPIO Zero is about the easiest way imaginable to get into Python GPIO tinkering, I think this will be really helpful for people. I’ve already been using the prototypes and find them an extremely helpful reference. Here’s what it looks like… It’s twice as […more…]

GPIO Zero Test Drive - Making Light of Security

Giving GPIO Zero (Beta version) a test drive might make you feel a little insecure, but I’m aiming to throw some light on the situation. I decided to try out some of the built-in features of GPIO Zero by working up a little hardware project. I looked at the current feature set and decided to try and combine MotionSensor, LED and LightSensor all at once. What sort of project uses that kind of technology? Why a PIR-controlled security light of course – if you swap the LED for a relay and 12V lamp! The video […more…]

If you’re a RasPi.TV regular, you’ll know that one of my very favourite things is hacking around with the GPIO ports on the Raspberry Pi and sharing my findings with the world. Sometimes this involves documenting a new feature, sometimes it involves making a new project, using a new chip or just getting something working that I haven’t tried before. But it nearly always involves Python programming and the brilliant RPi.GPIO Python library by Ben Croston. I’ve written all sorts of tutorials (~16) on RPi.GPIO because it is one of my favourite things. You may […more…]
