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.

Translated from: http://ricardo-dias.com/2010/11/20/arduino-wakes-my-pc/I've always dreamed of controlling something in my room through the Internet. Watch IPTV on the computer, turn on/off the lights, remote control peer download ... To do this, I need a server – my old desktop can do it. Of course, I didn't mean to hang it all day/week/month ... ^^I need to find a way to revive it whenever I want to. So I think I can use an

Author: huaqing visionary lecturer Before we use Arduino to achieve the lighting, flashing lights, serial lighting and the combination with the upper computer lighting. This time we will implement a UDP server to accept the command to implement the lighting, and to use the Intel Edison Development Board to achieve the lighting. First, the implementation of UDP lighting A UDP server is a normal way for network traffic to take. Use UDP protocol to achi

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

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
