An embedded-friendly method to determine whether a point lies within an area
Determining whether a point lies within a given shape can be tricky when utilising systems with limited resources. This post presents a light-weight methodology that uses cross-product multiplication.
Identifying strong object orientations within an image
Identifying an object’s orientation is a classic digital image processing task. In this post, we approach this problem using a Sobel-based methodology that responds to strong object edges.
A simple stepper motor control algorithm
This post presents a simple Arduino-based stepper motor control algorithm with adjustable acceleration/deceleration curves. Example code is provided, followed by a brief guide detailing some of the underlying theory, the hardware used for testing, and a breakdown of the Arduino code.
Communicating with the Dobot Magician using raw protocol
