have been very curious about how the Arduino timer is working, recently checked the atmega328p chip data, has now been atmega328p Timer1 timer as a description, control output matching pin D9 output level.The Arduino timer is available in normal mode, CTC mode, Fast PWM mode, and phase-adjustable PWM mode. This article uses the CTC mode, which is when the registerTCNT1 is equal to OCR1A/OCR1B (that is, matc

PreparationI didn't buy the original board. I purchased the compatible board from the authorized supplier. The compatible board has some changes.In order to connect the computer with the source board and the compatible board, you not only need to connect the cable, but also need to download the corresponding driver for the compatible board I purchased to use USB cable connection, the driver depends on the compatible board. Contact the supplier. Note that different drivers are required for differ

============================================= The first Arduino experiment was a Hello world experiment. Light an LED light, function is to let 13pin of LED lights flash once per second. The Arduino Uno motherboard comes with an LED light on the 13pin, which allows us to do some system diagnostic tests. Hardware: Arduino UNO R3 2012 motherboard piece, $52

I think you will see the URL below my first article, the official website of Arduino. When you go in, you will see the following picture: it already contains various versions, including Windows, MacOSX, and Linux, you can download the corresponding version based on your computer system. I use Windows XP. You can install the software. After installation I think you will see the URL below my first article, the official website of

Arduino Smart Car Production report production members: 20135224 Chen Shi 20135208 He Bong 20135207 Wang GuiPrerequisites:Arduino, an open-source, single-board controller, is built on the open source simple I/O interface and has a processing wiring development environment that uses a similar java,c language, using a software and hardware platform based on open-sourced code.

after the module test, make sure the ESP8266 is working properly and start connecting with Arduino to upload the data detected by the DHT11 temperature and humidity sensor to the monitoring platform. Prior to understand the platform has Yeelink and thingspeak, the principle should be the same, I choose Thingspeak here, we can try Yeelink, welcome to provide learning to share. put the results first.

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.
