Circuit Simulation: Mastering Arduino Open Source Hardware with Zero Investment

"Innovation for the Masses, Entrepreneurship for Everyone". Schools are increasingly emphasizing maker education, with enthusiasm rising as they begin to offer maker education courses and build maker laboratories when conditions allow, investing generously. However, many schools are financially constrained and struggle to find a starting point. Indeed, many friends say that hardware has become cheaper, with counterfeit versions costing less than 20 yuan, and DIY options around 10 yuan, but the reality is that applying for hardware requires a plan,

Recommended Components for NodeMCU Experiments

Experimental components include: LED, switch and temperature and humidity sensor.

1. Connection of LED

LED (Light Emitting Diode) is a solid-state semiconductor device that can convert electrical energy into visible light. It directly converts electricity into light. The core of the LED is a semiconductor chip, one end of which is attached to a bracket, one end is the negative electrode, and the other end is connected to the positive electrode of the power supply, encapsulating the entire chip in epoxy resin.Note:

Process Interaction in Raspberry Pi Using Python Queues

Introduction

Currently, there is a task requirement for the shopping cart, which involves image recognition and motion control. Therefore, it is necessary to initialize two processes to complete the respective actions. Since motion control requires the results of image recognition, we now need to implement the collaboration between the two processes using Python syntax. This blog combines an actual Python program to achieve process interaction through queues.

Program Analysis

First, let's introduce the libraries we need:

import time
from multiprocessing import Process, Queue

01 CPU vs FPGA

It vividly expresses the computational logic of CPU and FPGA. The CPU tends to be multifunctional and usually executes instructions serially. Although it has multiple cores, each core still executes in a serial manner, the design of the CPU is aimed at executing a wide range of tasks, including operating systems, applications, algorithms, etc. On the other hand,

Overclocking Methods for Raspberry Pi 400

Overclocking the Raspberry Pi 400 is very easy to achieve. In terms of heat dissipation, the Raspberry Pi 400 is designed with a large passive heatsink, which is very useful. There is no need for additional active cooling to meet the heat dissipation needs of overclocking.

Although some users have configured the Raspberry Pi 400 to overclock to 2.2GHz, I believe that 2GHz is more stable.

Overclocking Settings

Here are the steps to configure overclocking on
