Source of demand1. My son finished the year 6 years old, like to play fireworks, but the courage is small, so I am responsible for ignition, from the year before 26 to the beginning of eight, every night to give his son point firecrackers ah point firecrackers.2. The new year to open the door gun and opened the gun, Lunar New Year early morning also to help mom point firecrackers, said the whole string of small firecrackers also fried too fast, every time did not run a few steps on the open, bro

First Arduino default I²c address is 7-bit address, the manual is described, 7-bit address is 0x1e, read address is 0x3d = (7-bit address If you want to communicate with the hmc5883l, you need to hmc5883l power on the 5ms. Therefore, the general write configuration requires a delay of 5ms before communication. After connecting the device to test the sensor, identify the operation and identify register a, identify register B, identify register C is

Recently suddenly want to study STM32, see almost all of the tutorials are used in C-Series microcontroller program, so that has been studying C 艹 I write very not adapt to, today studied for a noon, successfully a single LED driver package into an Arduino-style class library, the use is very convenient, the method is as follows.Before you begin, it is recommended that you follow the methods described in this article in the STM32 template creation met

Arduino relatedArticleNow, I recently bought a Bluetooth chip (bluetooth module JY-MCU) online, which is also 37 yuan cheaper This chip uses the Bluetooth serial port service, which is encapsulated by Arduino. That is, the connection line reads data and writes data through the serial API,ProgramCodeIt is also very simple The only trouble is that you can write applications on your mobile phone. I

Summarize the experience of wireless module debugging. There are already people on the Arduino who have made the library of this module, but according to the manual written also has a certain reference significance.Wireless module is one of the modules that I think is more difficult to debug, because it is a module of mutual interaction, communication failure has two reasons, can not be found from a single code. The code is written, and all sorts of i

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
