Use a TensorFlow SSD MobileNetV2 DNN on the Raspberry Pi plus Pi Camera to build an autonomous car capable of object detection. Story This project will show how to transform a (Raspberry Pi... Read more
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 centre taps. B... Read more
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 in C and I... Read more
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’s wha... Read more
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 example of... Read more
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 handles everyth... Read more
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!) He asked i... Read more
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 some importan... Read more
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 applications. The... Read more
