Building a Raspberry Pi Robot and Controlling it with Scratch Happy New Year everyone! Things have been a bit quiet on this blog due to the Christmas rush, and the fact that we’ve been spending time on product development (more on that in a future post). But here at last is the 3rd and final post in our series on the Raspberry Pi robot we […] Welcome to the second part of our series of posts, describing the workshop we ran at the recent Digimakers event at @Bristol. In the last post we described the outline of the workshop and looked at the hardware of the Raspberry Pi robot that we built for the event. In this post we describe the […] Last weekend we ran a workshop at the Digimakers event at @Bristol where we taught people how to program a Raspberry Pi robot with the Scratch programming language. We had a great response to a recent blog post we wrote, describing how to build a Raspberry Pi robot that you can drive around using a tablet, smartphone or PC. Update: This post is now out of date as we’ve released a new version of the software.
Using a camera with Scratch on the Raspberry Pi | Matthew Venn I needed camera control with Scratch on the Raspberry Pi for a primary school aerial photography project. I added a new python extension for Simon’s ScratchGPIO that allows either the Raspberry Pi camera or a regular USB webcam to be used with Scratch. Follow Simon’s instructions for installing over on his site. Add your camera – if you’re using the Raspberry Pi camera, follow their instructions here. After you’ve started scratch, all you need is to make a broadcast block and set it’s message to ‘photo’. This program starts automatically, then in a loop flashes an LED on pin 8 and takes a photo. Photos are stored in /home/pi/photos, each photo has a number that increases as the photos are taken. Make sure you delete/backup your photos regularly or you’ll run out of space fairly fast!
