Similarities and differences between Arduino and C + + The cause is this: I want to play Arduino, play for a while, I would like to write some of their own library, easy to operate. So the cheap in C + + wrote a library, the results found below a few points, a little chaos, only for memory and reference: (the direction is changed from C + + to Arduino) string rf

Memsic2125 Acceleration Meter MEMSIC2125 is a two-axis accelerometer that can measure the acceleration of positive or negative 2g in two directions (g represents the gravitational acceleration). Its pin design is simple: Only two data output pins, one for the x axis and one for the Y axis. Its data output pins will output different pulse widths according to the size of the acceleration (do not know what the pulse width is please see this article). The subtle level of pulse width can be measured

Today took out the home Arduino again out to play a bit, also looked at some recent online information. Feel the current online article still stay in this how to use, that how to use the stage. There are few examples of the combination. So, I will write the code today, for everyone to refer to the brick. Arduino, after all, is the basis of C language. So the structure of the program is still very important.

This example uses the 'lilypad 'link mpu6050 module, 'arduino uno' as the USB download device, the specific connection method please move: http://www.cnblogs.com/hangxin1940/archive/2013/04/06/3002709.html # How to connect lilypad to mpu6050!

Before writing a post about the Arduino timing, the Arduino library has external interrupt function, but the function of the internal interrupt is not mentioned, this article intends to use the Arduino timing interrupt to write a blink program.The code is as follows.1 /*******************************************************************************2 ***3 *project

The answer is yes. There are 26 pins on the Raspberry Pi Board, these gpio (general purpose I/O) including SPI, I²c, serial UART, 3V3 and 5V power supply. Domestic forum There is an article "RASPBMC Setting Infrared receiver" describes how to install the RASPBMC operating system for Raspberry Pi, install the infrared receiver for remote control. The following figure defines the 26 pin pins for the Raspberry Pi Raspberry Pi is much more expensive than an ordinary

analog signal Output [Mega] This session uses the Arduino mega or Genuino Mega board to allow 12 LEDs to be dimmed one after the other. The reason for using Mega is because it has more pins that support PWM operations. The hardware required to complete this example Arduino Mega or Genuino mega board 12 x Red LEDs 12 x 220ω Resistors Jumper Bread Plate DuPont Line/C

Buy MPU6050 self-contained attitude solver greatly reduces the work done by the upper processor. By getting acquainted with the processing after doing a small example is to feel the magic of this sensor. Arduino sectionThe main is to read MPU6050 data and the acquisition of Euler angle through the serial port printing to the host computer, the acquisition of data is very simple, MPU6050 received the Arduino

Android adk with a standard Arduino UNO and USB Host shield a few weeks have past since my last post and a lot was going on. First off how great was Google io? I Hadn't the chance to participant ipate personally but I watched a lot of sessions online and was amazed of what Google had up its sleeve. new APIs, services, best programming practices but most importantly a lot of great talks about Android. as a software and hardware tinkerer I was gglad to

Arduino can be used to develop completed electronic components such as switch or sensors or other controllers, LEDs, stepper motors or other output devices. Arduino can also operate independently as an interface that can communicate with software, such as flash, processing, MAX/MSP, VVVV, or other interactive software .... The Arduino development IDE interface is

The principle is not complex, because arduino is already a database with a bunch of avr +, just find a tool that can compile and translate hex and download it to the board. However, we still encounter many problems. First, make: Interrupt/Exception caught (code = 0xc00000fd, addr = 0x4217b3) appears during eclipse + avr plugin compilation) Make cannot contain spaces like Program Files in the path.
