Arduino is a versatile computing platform to work on microcontrollers and embedded systems. It can be used to write programs and run on microcontrollers. These boards comes with on board LED which can be as a hello word Arduino program. To extend the functionality and to interface with external physical world we need do lot […]
When you develop a new deep learning model, it should be trained with a huge input dataset. When the input training dataset size is small for computer vision applications, the performance of the model can be increased with Image augmentation. Image augmentation is process of creating new dataset from the existing images with few image […]
Transfer learning is a process in Machine Learning to reuse models that are already developed and trained with the huge dataset. Transfer learning is widely used in computer vision applications because the models are pre-trained with the Imagenet database. it is a widely accepted technique, popular in machine learning because training a model needs a […]
LCD or Liquid crystal display is a common output device used for embedded, IoT devices, industrial control, and medical devices. To display simple text messages, alert messages and keypad entries from user Alphanumeric LCD or character LCD is easy to use and takes less GPIO from the microcontroller. In general Alphanumeric LCD comes with dimensions […]
Image segmentation is an essential operation for extracting objects and features from an image. In general object- extraction is an important step in different advanced image processing operations. Among many different ways of segmentation, thresholding is one of the segmentation which produces a binary image. The binary image is an image with pixel values either […]
OpenCV or Open Computer Vision Library is one of the widely accepted opensource Library for image processing and computer vision applications. OpenCV supports Python, this feature makes OpenCV as the default choice for Deep learning application for computer vision. This blog post shows how basic image processing operations can be carried out using Python OpenCV […]
In this article, we look at using TB6612FNG motor controller, and the gpiozero python library for controlling DC motor. TB6612FNG motor driver has widely used for applications where better efficiency and performance is required. Below schematic shows the Raspberry PI zero GPIO connections to the motor controller. TB6612 motor controller can driver two motors simultaneously, […]
DS18b20 is a simple temperature sensor which gives digital output on single I/O pin based on 1-wire protocol, so this can be used with the Raspberry-Pi without the need of Analog to Digital Converter (ADC). On Raspberry Pi, 1-wire interface can be enabled by using sudo raspi-config utility, select “Advanced Option” and enable the 1-Wire […]
In programming timer are used to perform a particular operation at regular interval, or later some time. Linux userspace programming support Alarms to support timing related operations. In this blog post we will discuss how to achieve timer or timing related operations in Kernel space. Linux kernel provides software timer interface in kernel for device […]
In Linux, the character devices are used for transferring a small amount of data from user space application to Hardware device, similarly, this interface is also used to receive data from Hardware device to userspace application. In this article we develop a simple Linux character driver for Turning on LED connected to Raspberry-Pi GPIO, and […]
