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

calibration of analog signals This example shows you a technique for calibrating a sensor: Read the sensor value for 5 seconds at startup, then look for its maximum and minimum value. The maximum and minimum values after calibration will be useful in the map function. complete the hardware device required for this example Arduino Board or Genuino board LED Analog signal sensor (photoresistors on OK) 10kω Resistor 220

Espcomm_send_command:didn ' t receive command Responseespcomm_send_command (flash_download_begin) failed I now have two boards that have this problem, and I've been trying to solve this problem for a long time. There is no similar problem at all in domestic articles. Constantly try online solutions, mainly because their English level is too poor to view foreign documents, quite labored. 4 o'clock in the morning I get up and start to make, finally in my constant try, I finally solved the problem,

If you are using a compact Windows system, you may encounter the problem of "system cannot find the specified file" When installing the Arduino driver, as shown in the following figure: This is because the compact window system deletes some of the less commonly used driver information, and the workaround is as follows: 1.

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
