Arduino Hardware combination Platform (i)

Recently studied Arduino, ready to do a combination of control systems.The general idea is that the utility of multiple Arduino into a combination network for communication and distributed control1. A WiFi module with ESP8266 connected to a UNO Ardunio board to do the total route2, the total route Arduino called Ra,ra on a number of virtual serial ports and I²c i

Some Arduino test code

1. HC-SR501 Human Body infrared sensor module test // Infrared sensing // Signal to port 7 Int Ledpin = 7 ; VoidSetup (){Pinmode (ledpin, input );Serial. Begin (9600);//Open the serial port and set the baud rate to 9600 bps.} VoidLoop (){IntIn= Digitalread (ledpin );Serial. println (In);//When someone is there, the output is high. 1 nobody is 0.Delay (2000); } I bought a module in this way: if it is placed on a car, it can sense whether there are people around it. If

How does the Arduino development tool work?

1, download and unzip the software, small series is extracted to the desktop, we can not do so, small series is just a demonstration, because the small part is not used this. Then open the folder. As shown in Figure 1. Figure 1 2, find "Arduino.exe", double-click "Arduino.exe" to run. The main interface of the Arduino will appear. As shown in Figure 2. Figure 2 Figure 2 provides a simple functional callout for the

Arduino's solution for driver installation failure on AMD64 win8.1

prompt for system files not found when updating drivers manuallycause of the problem:we can open C:\Windows\inf\setupapi.dev to open the hardware installation log. Finding the last record, we will find the following error:sto:copying driver package files to ' c:\users\admini~1\appdata\local\temp\{7ff41925-97db-1c6a-d5b E-311dd1322b22} '.inf:opened inf: ' D:\arduino-1.0.2\drivers\arduino uno.inf ' ([strings]

arduino-Serial Communication

The USB interface used by the Arduino to communicate with the computer is the USB interface used to download the program, and when Arduino communicates with other devices, it needs to use the "Serial" series of functions, so we have to know about it, here are a few common " Serial"function.1, Serial.begin ()-Sets the rate at which the serial data is transmitted per second (baud rate). When communicating wit

SR04 Acoustic Sensor principle and Arduino programming--everyone can play hardware _arduino

Through the first two articles, we have become familiar with the basic GPIO programming of Arduino and the serial communication between PC and Arduino. Next we're going to start learning all kinds of sensor operations while delving into Arduino programming. Before we start programming, we need to be familiar with the principles of SR04. Here is a digression: the

Full analysis of hardware design for Arduino UNO Development Board

This article focuses on how the Arduino Development Board works from a hardware perspective. Most of the articles are about Arduino software. However, an in-depth understanding of its hardware design can help you take a solid step in the Arduino journey. Mastering the electronic design of the Arduino hardware will hel

The use of several common "Arduino" sensors

The Arduino timer function

have been very curious about how the Arduino timer is working, recently checked the atmega328p chip data, has now been atmega328p Timer1 timer as a description, control output matching pin D9 output level.The Arduino timer is available in normal mode, CTC mode, Fast PWM mode, and phase-adjustable PWM mode. This article uses the CTC mode, which is when the registerTCNT1 is equal to OCR1A/OCR1B (that is, matc

Arduino Hello 2

PreparationI didn't buy the original board. I purchased the compatible board from the authorized supplier. The compatible board has some changes.In order to connect the computer with the source board and the compatible board, you not only need to connect the cable, but also need to download the corresponding driver for the compatible board I purchased to use USB cable connection, the driver depends on the compatible board. Contact the supplier. Note that different drivers are required for differ
