Using a camera with Scratch on the Raspberry Pi
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. If it’s a USB camera then just plug it in. 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!
