Arduino-based home anti-Leech (original)

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 obtains the PPM control signal from the model remote control receiver

Wireless remote control uses high-frequency radio waves to control the model. For example, the 6-channel 2.4 GHz Remote Control of wfly, a set of more than 200 pieces, with automatic frequency hopping anti-interference capability, theoretically, we can allow hundreds of people to remotely control their models at the same site without interfering with each other. In addition, the remote control distance is also quite advantageous. The power of the 2.4 GHz remote control system is only less than 1

Arduino data type conversion (single chip) detailed introduction _android

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 (

Read data from the Internet using the Arduino Development Board and ESP8266

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

Design of an Arduino alcohol tester

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
