Share this:Bi-polar stepping motors use only two coils and are easily recognized because they only have four wires. Most unipolar steppers can be used in bipolar mode by ignoring the two cen... Read more
Share this:I have experimented with GPIO on the Raspberry Pi, just turning an LED on and off here. But since then Ben Croston has improved the RPi GPIO Python library to do most of the work... Read more
Share this: In my last instructable, I covered how to run a shift register using a Raspberry Pi, and kind of hinted that one thing you could do with it is run an HD44780 based display. That... Read more
Share this:There’s something exciting about crossing the boundary between the abstract world of software and the physical ‘real world’, and a relay driven from a GPIO pin seemed like a good... Read more
Share this:The max7219 lets us control lots and lots of LEDs using just a few Raspberry Pi pin-outs. No hassles with multiplexing, latching, refreshing or using up all your outputs – it hand... Read more
Share this:This is a small project I did for a colleague who is building a 1/48 scale RC model of a Fletcher class Destroyer (yup…that makes the “model” about 8 feet long!)... Read more
Share this:This post will be the first of a series of posts that will describe how to drive a 7-segment display from a Raspberry Pi, without any OS running in it. Today, I will talk about so... Read more
Share this:Stepper motors are versatile devices that allow precise and repeatable angular control. They are used in disk drives, translation tables, and 3D printers to name just a few applic... Read more
