I’ve discussed driving a stepper motor and ultrasonic distance sensor in previous posts. In this one, I’ll bring it all together and outline the Scratch based ultrasonic room scanner. Continue reading “Scratch Ultrasound Room Scanner”
I followed the numerous tutorials on getting WordPress working on a Debian based Linux box. I’m doing this on Raspbian on a Raspberry Pi, but I expect the same gotcha to apply to all distros. The problem is the Cant Create Directory message when updating or installing themes and plugins. Continue reading “Getting WordPress to work on Debian based systems.”
Back in part one, I described a project involving an ultrasonic distance sensor mounted on a stepper motor, all controlled with Scratch on a Raspberry Pi. Here, I’ll describe the sensor.
A few days ago I created a project in Scratch on a Raspberry Pi 3. The plan was to mount an ultrasonic distance sensor on a stepper motor and have it scan the room drawing a picture of the room as it went. In this part, I’ll talk about the stepper motor and how it’s controlled.
Yay, I got first post. But I guess I’m bound to with this being my blog.
