This project demonstrates how to implement a PID based DC motor controller using Raspberry Pi. DC motor controller program is developed using Python. It consists of a GUI, RPM measuring, error detector, PID controller functions, and PWM generation function. The PID based closed-loop DC motor control system is one that determines a difference in the required speed and actual motor speed and creates a correction control signal to remove the error. To learn more about PID controller and DC Motor, g ...
This project is done with Open Source Computer Vision Library (OpenCV). OpenCV was designed for computational efficiency and with a strong focus on real-time applications. So, it's perfect for real-time face recognition using a camera. To create a complete project on Face Recognition, we must work on 3 very distinct phases:Face detection and data gathering, train the recognizer and face recognition. we will simply create a data-set, where we will store images for each id, a group of photos that ...
Recently I came across the nanonets.io website which provides APIs for image classification and detection. The one thing that caught my eye is the ease of use. Whenever you work around AI, it involves two steps, first is the training where a model is created from known data sets and the second phase involves the classification of unknown data by using the obtained model. The model’s accuracy increases as the training data sets size and quality increases. This is important because the image ...
