Ultrasonic Sensor Sweeper with Servo and Arduino Code

This guide uses the HC-SR04 Ultrasonic Distance Measuring Sensor mounted on a 9g type servo motor. The guide also features the servo and sensor bracket kit that is available to buy. Also, I include the Arduino code that will demonstrate the sensor sweep functionality. To follow this guide you can use any servo and sensor bracket you have to make use of the Arduino code below.

OLED Display Library Setup for the Raspberry Pi featuring SSD1331

Thanks to an impressive Python library, we can connect various types of OLED displays to the Raspberry Pi such as the SSD1331 colour display. So to get this vivid, high-contrast 16-bit colour display up and running, I take a look at how to set up this library from  Luma.OLED. Additionally, I also show how to install and run the many examples available. Continue reading “OLED Display Library Setup for the Raspberry Pi featuring SSD1331”

Motor Driver for Raspberry Pi Robot using TB6612FNG

In this feature, I take another look at the TB6612FNG motor driver, but this time, with the Raspberry Pi instead of the Arduino. The H-Bridge module is the chosen robot driver for my Pi Wars entry effort. View this post for circuit examples and Python test code to get started with your own Robot Project.

Pi Camera Video Capture with OpenCV and Python Multithreading

In this article, I install the Raspberry Pi Camera which I will be using to add camera vision to a robot. Also, to maximise the performance of OpenCV and Camera, I will be using a utility to add multithreading to the Python applications. Furthermore, I include Python demo code which also supports USB webcams. Continue reading “Pi Camera Video Capture with OpenCV and Python Multithreading”

Nokia 5110 LCD Display Setup For Raspberry Pi Guide

The Nokia 5110 LCD Display seems a perfect fit for the Raspberry Pi as the screen can be connected directly. So here is a guide on how to set one up with details on how to hookup and install libraries. Also included is an example Python program in addition to the code examples included with the libraries.

Install OpenCV onto Raspberry Pi from Shell Script

This article is a quick guide on how to install OpenCV onto the Raspberry Pi – the easy way. I will introduce a shell script that will install OpenCV and dependencies without user intervention. Furthermore, I will also introduce GNU Screen so that the OpenCV installation can be done remotely in a Virtual Terminal Session. Continue reading “Install OpenCV onto Raspberry Pi from Shell Script”
