[Data processing] python Matplotlib partially enlarges the figure; marks the local enlarged subfigure of interest
Foreword In data visualization, it is often necessary to partially enlarge the data in a certain interval to obtain a higher contrast visualization effect. The following uses the Matplotlib library of the Python language to implement a simple partial magnification effect. Dependent libraries matplotlib: plotting library numpy: an extended library that supports a large number […]
Design of fully automatic washing machine based on 51 microcontroller
Design of fully automatic washing machine based on 51 microcontroller (Simulation + Program + Schematic + Design Report) Function introduction Specific functions: 1. Set 4 washing modes: “standard”, “economy”, “individual” and “drainage”. 2. Divided into strong washing and weak washing (motor speed). 3. The process is divided into “water intake”, “rinsing”, “washing” and “dehydration”. 4. […]

React technical principles and code development practice: React form processing and verification
1. Background Introduction Currently, front-end technology is changing with each passing day, and new technologies are emerging one after another. React, as the most popular Javascript library at the moment, is increasingly favored by developers. React is known as “the Facebook of JavaScript”. Its advantages include componentization, declarative programming, JSX syntax, etc., and React Hooks […]
FPGA generates 3X3 image processing matrix through FIFO
In the previous series of articles on median filtering, I have written about the generation method of 3×3 matrix template: Median filter design based on FPGA—-(3) Matrix template generation module design_verilog image generation 3*3 matrix-CSDN blog Now it seems that this method is relatively crude and simple. The general processing method is to store an […]
51 microcontroller + DS1302 design an electronic clock (LCD1602 displays time)
1. Preface An electronic clock is a device that can accurately display time. It is widely used in homes, offices and public places, providing people with convenient and accurate time information. This project designs an electronic clock based on 51 microcontroller, using DS1302 as the RTC clock chip, LCD1602 as the display screen, and connecting […]
Java interface-oriented – rock paper scissors
Interface development process Define the interface. The interface defines the method name and does not need to be implemented. All developers must implement the interface for development. Inheritance is single inheritance, and cascading achieves multiple inheritance. Interface (which module to develop), multiple inheritance For methods that are not implemented, you only need to limit the […]
