arduino trackball

developed in Arduino without worrying about boring compilation and machine code, because the Arduino IDE has a Processing/Wiring development environment similar to Java and C language. Environment installation and setup is also very convenient, you can download the installation package from the http://www.arduino.cc, installation.

Evil modification: TPYBoard makes cheap WIFI jammers and tpyboardwifi Reprint Please note: @ small Wuyi http://www.cnblogs.com/xiaowuyi 0X01 Introduction Do you want to have a Wi-Fi jamming device? I collected some information on the Internet and found that esp8266 can be used to implement simple interference functions, including network disconnection, replication, and spoofing. I have a Tpyboard V202 (30 yuan) in my hand, which is also an esp8266 chip. I also want to change the firmware. Can th

The method of increasing sonar height by MWC flight controlPresent situationMWC Open source flight control has been a bit of a year, and now a lot of new cross-machine to cc3d, Aerial camera switch to APM, commercial flight control is also a lot. But MWC as an Arduino based open source flight control, can be said to be very mature and code easy to understand, cheap, the effect is good, so my four-axis platform is still using the MWC flight control.

LED Control MethodHere, the built-in led driver and control method of tiny6410 are directly used for LED control. The method is as follows: 1. Register a switch sensor according to reference 1. 2. query the status of the switch sensor based on yeelink api. Use shell scripts on tiny6410 linux. #!/bin/ YL_ApiKey= YL_URL=http: upcmd= $upcmd | > /dev/sh

impossible to have too many built-in or plug-ins with additional hardware. Arduino breaks through the volume limit of mobile phones and combines android with the motherboard of a general handheld device. With this general-purpose motherboard, you can not only develop tablet computers like iPad, but also various remote control devices, including robots [16].

command. Example 3: 1. Set the pause for each action for 5 seconds or another time period until an error occurs. At this time, you can have more time to view the execution process of each action. 2. After an error is found, change the source code. After the error is changed, perform the same seed value and the same starting position to test the same event again. 3. If the error does not occur again, perform another SEED value test. It is a stable enough program until it has been proven to be c

for your users, when you want to inherit a view class, you might be able to use it once to create a custom component. Maybe you want to inheritButtonclass to make something more beautiful.In such a case, you might need to define a default event behavior for your class, using the event handler for the class handlers. Event listener an event Listeners is an interface in the view class that contains a simple callback function. These methods will be called by the Android framework when the listener

This tutorial will teach you how to install the latest ArduinoIDE1.6.7 in the current Ubuntu15.10 release. Open-source ArduinoIDE released 1.6.7 and brought about many changes. The new release has been switched to java8. it is bound to the IDE and used for compilation. For details, see the release description. For older versions 1.0.5 that do not want to use the software center, you can install Ardui in all Ubuntu Distributions Using the following steps This tutorial will teach you how to instal

Sometimes, I prefer Arduino over cubieboard. Let's talk about the PWM problem first. Now there is no complete PWM driver on cubie's A10, and it is not enough and inconvenient to use, and some things such as IR are very mature in Arduino.So I started a hardware program for huluyun.1 huluyun is a real Arduino, and its design makes it easy to connect to CB. When buying it, it comes with four dubang lines 2.54
