sensor detects a move and the output is high, if the human body continues to move within the detection range, the sensor remains high, knowing that the person leaves before the delay turns the high level to low.differenceThe difference between the two detection modes, after detecting the movement trigger, if the human body continues to move, whether the continuous output high level. hc-sr501 simple function Experiment
Next, we will try to complete a simple experiment to use this sensor.First we
Always heard that many do IoT, smart Home controller using the Arduino, studied brother there got an Arduino development board, a afternoon study, feel this suitable for children play:)Talk less, sum up, it is easy to use later. I mainly refer to the Baidu Library of a 60+ page of "Arduino from scratch" and some technical forums such as Geek Workshop bar. As a re
When there is a theft incident in the community, do you always worry about the theft of your home on the subway at work, in front of your computer at work station, during a late night gathering, or when you are traveling?Now let's talk about how to DIY an Arduino-based home anti-leech!Before DIY, design the DIY process first! In order to express myself in a concise way, I can paste my own picture! In my opinion, the original intention of DIY is to use
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
DescribeAn Apple Watch and iphone app for controlling any infrared device. The iOS app sends an HTTP request to one or more Arduino with an Ethernet board. Arduino is parsing an HTTP request and sending an infrared signal. The Arduino code is based on the Irremote Library (https://github.com/shirriff/Arduino-IRremote).
