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

SI7021 is a temperature and humidity sensor chip produced by Silicon Labs. Its main features: Humidity accuracy: Error typ. +/-2%RH, Max +/-3%rh (0~80%RH), factory corrected Temperature accuracy: Error typ. +/-0.3%°c, Max +/-0.4%°c ( -10°c~85°c), factory corrected Measuring range: Temperature range 0~100%rh, maximum temperature range -40°c~125°c Operating voltage: 1.9~3.6v Low power consumption: Low 150μa at work, 60nA at standby Interface: I²C, maximum rate support

After the download is complete, you can find the following version file: Arduino-1.8.2-windows.exe This is the latest version and will be updated as time progresses. When you insert the

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. GPS Software Requirements · Ardiuno Software · Monitor serial 1 to receive data. · Da

Arduino MQ135 Gas Sensor first, the wiring 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.

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

: Using the Atmel Atmega168 328 processor, because of its many supporters,The company has developed a 32-bit MCU platform to support Arduino.The current Arduino Control Panel is the latest Arduino Uno, as shown below:Domestic use of more than the Arduino Duemilanove 2009, the main reason isUNO's USB control chip package changes, manufacturing costs rise, other ch

============================================= 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

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.
