arduino trackball

Trackball Mouse: The mouse is mostly used in laptops, the shape looks like a reverse mechanical mouse, its internal principle and mechanical mouse has a lot of similarities. Its greatest advantage is that it does not have to run around like a mechanical mouse, saving space and reducing the fatigue of the user's wrist. Relative to the general mouse, track ball due to its design characteristics, positioning accuracy, not easy to shake and other

When programming to Arduino, because there is no debugging tools, often through the use of serial communication to call Serial.print and SERIAL.PRINTLN output Arduino running the relevant information, and then on the computer with the Arduino The IDE's serial monitor to see the print out information. Serial Monitor not only accepts data that

Hello everyone, I'm a small-story,Remember the previous section click the Open linkWe're talking about the Arduino Foundation today.First download the program on the Arduino official website.Windows Decompression versionVersion of the Apple systemOK, download the programming software. Let's just talk about programming.This is a programming language similar to C + +.void Setup () { }This is the initial stat

Reprinted please indicate the source: http://blog.csdn.net/lxk7280 First, give a preliminary understanding of the main things to be used. There are two categories: hardware and software. Hardware, that is, Kinect. Software, I .e., Arduino and processing. Arduibo is believed to have been used by many people. Many electronic products such as robots and quad-axis aerial vehicles are related to the romantic compiler of

Arduino car entry-fourth day (sensor), arduino car Hello everyone, I am a small Editor. Record the content in the previous section and click "open link ". Today we will talk about sensors. Today we will talk about light and ultrasound. Start with a chart: There are three optical interfaces: UCC, out, And GND. Ultrasonic has four interfaces: UCC, T, E, And GND. The following is the principle. The ultrasoni

I'm with Arduino, and why write this series of articlesArduino has been on fire for years, and it's not a new technology. If someone is not clear about what Arduino is, I'm sorry, please search by yourself, open any Wikipedia introduction or a fan of the series of articles, people introduced more than I know more comprehensive. I'm afraid I don't have to repeat it here.The first contact with

The Arduino pro mini is a micro-control panel based on atmega328 and supports 5 V/3.3v voltages. However, the default voltage is 5 V. How can we make this board support 3.3v voltage. Preparations 1. If you have never used Arduino, You need to download the IDE first. The installation method is not described here. 2. Prepare two board boards, one of which is our Arduino
