GPIO PWM For Raspberry Pi H-Bridge DC Motor Control
In this article, I look at using the Raspberry Pi GPIO PWM for DC motor control. Through Python programming, I look at how to interface with a typical H-Bridge DC motor driver. Furthermore, H-Bridge diver code examples with wire connection illustrations are included. Continue reading “GPIO PWM For Raspberry Pi H-Bridge DC Motor Control”
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”
Robot Control with Raspberry Pi and Python
To get my Raspberry Pi robot moving, I need a wireless robot control system. So, in this article, I connect a game controller to the Raspberry Pi and use Python programming to manage the input commands. Included, is a controller button-ID map and Python base-code to translate controller inputs. Continue reading “Robot Control with Raspberry Pi and Python”
