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.

Arduino Data type Conversion How to easily play Arduino SCM, when I was in the data conversion, encountered a problem, try C language and C + + many functions, did not achieve the float data conversion to char type. After hard access to the data, finally found a great god-level function!!! DTOSTRF (), you can easily implement data types from float to char. Get it The format is as follows: char* DTOSTRF (

ESP8266-01 is a powerful module that can meet the needs of any of our IoT projects. Since its release, it has formed a very powerful community and evolved into an easy-to-use, inexpensive and powerful Wi-Fi module. Another popular open source platform is the Arduino Development Board, which has built up a large number of projects around the platform. Combining these two platforms will open the door for many innovative projects, so in this tutorial we

In this project, I'll show you how the Arduino connects to the alcohol detection sensor. Here, I have designed an Arduino Shield circuit board using the Easyeda online PCB designer. The Arduino Alcohol Analyzer detects the amount of alcohol in the breath, and then, by some calculations in the code, we can calculate the amount of alcohol in the breath or blood, an

analog signal Output [Mega] This session uses the Arduino mega or Genuino Mega board to allow 12 LEDs to be dimmed one after the other. The reason for using Mega is because it has more pins that support PWM operations. The hardware required to complete this example Arduino Mega or Genuino mega board 12 x Red LEDs 12 x 220ω Resistors Jumper Bread Plate DuPont Line/C

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

Android adk with a standard Arduino UNO and USB Host shield a few weeks have past since my last post and a lot was going on. First off how great was Google io? I Hadn't the chance to participant ipate personally but I watched a lot of sessions online and was amazed of what Google had up its sleeve. new APIs, services, best programming practices but most importantly a lot of great talks about Android. as a software and hardware tinkerer I was gglad to

Arduino can be used to develop completed electronic components such as switch or sensors or other controllers, LEDs, stepper motors or other output devices. Arduino can also operate independently as an interface that can communicate with software, such as flash, processing, MAX/MSP, VVVV, or other interactive software .... The Arduino development IDE interface is

The answer is yes. There are 26 pins on the Raspberry Pi Board, these gpio (general purpose I/O) including SPI, I²c, serial UART, 3V3 and 5V power supply. Domestic forum There is an article "RASPBMC Setting Infrared receiver" describes how to install the RASPBMC operating system for Raspberry Pi, install the infrared receiver for remote control. The following figure defines the 26 pin pins for the Raspberry Pi Raspberry Pi is much more expensive than an ordinary

The principle is not complex, because arduino is already a database with a bunch of avr +, just find a tool that can compile and translate hex and download it to the board. However, we still encounter many problems. First, make: Interrupt/Exception caught (code = 0xc00000fd, addr = 0x4217b3) appears during eclipse + avr plugin compilation) Make cannot contain spaces like Program Files in the path. Copy one copy to the root directory. Then the comp
