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

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
Arduino Port Code:
int red=255; Create variables to store the data to be sent
int green = 2;
int blue = 3;
void Setup ()

serial.begin (9600);//define a data transfer rate of 9600 bits
}
void Loop ()
{
serial.print (red);
Serial.print (",");

Above red, Green,blue is replaced with the value obtained by the color sensor in the actual app
the problem may occur. The system installs the basic use software, Sogou Input method, Smplayer,tweak and so on, the robot software has the gazebo, has loaded the necessary model storehouse, avoids because the network problem appears the space map the situation; V-rep's edu version, install Rosby example and Learningros for Robotics Programming-second Edition all the libraries, including Opencvnon-free.

Description
Reads the value from the specified analog pin. the Arduino board contains a 6 channel (8 channels on the mini and nano, 16 on the mega), 10-bit analog to digital converter. this means that it will map input voltages between 0 and 5 volts into integer values between 0 and 1023. this yields a resolution between readings of: 5 V/1024 units or ,. 0049 Volts (4.9 mV) per unit. the input range and resolution can be changed using analogreference

This blog tells me the idea and implementation of using Arduino to parse and forward raw NEMA 0813 data. Because Arduino is relatively simple, can not realize the serial data receive interrupt, so are written in the main loop inside. Do not know what flaws and loopholes in the code, you are welcome to criticize correct.

The MQ135 has 4 pins, VCC, GND, A0, D0, respectively, where VCC, GND, and A0 are required. The following diagram is a esp8266 wiring diagram. Due to the measurement of the gas value of PPM, it is related to the air temperature and humidity. So we've added a DHT22 here. DHT22 Portal

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
