Yesterday made the control led, played the first, the rest of the feeling is very simple, here recordJust a couple of photos.Play the honey module only to find the law, generally this module, there will be three pins, VCC (3.3V or 5V power supply output PIN), GNC (for Gpio pin of GNC), out/(I/O) (corresponding to the gpio number of pins), if it is necessary to send information to the Raspberry Pi, This modu

Introduced The DHT11 is a cheap accessory that includes temperature and humidity sensors, and the code is easy to use. This article describes if you use DHT11 in a Raspberry Pi, the code is python. If you have any questions, please leave a comment below. Wiring VCC Connection 5V or 3.3V Data is connected to the Gpio (I'm picking up the BCM pin 16th, the physical pin is 36) GND Co

[2] when the air conditioner in the room is turned off, the Raspberry Pi CPU temperature increases from 42.2 degrees to 47.1 degrees, in line with actual expectations, indicating that the experiment was successful. [3] Let's use another example to store the temperature to the database, and use another restful API to read historical temperature data. [Tucao] The yeelink platform has

files from a remote server.My other Raspberry Pi was once used as my git repository. To tell the truth, the memory was a little too powerful, installing and deploying gogs through docker is the most agile way to build a git repository. Of course, I will also bring a temperature and humidity sensor to the old employee and push it to the server through websocket.

, and intelligently judge with shell scripts to synchronize files from the remote server.And my other Raspberry Pi is a battle-hardened, once used as my Git repository, to be honest, the memory is a bit overwhelming, the installation and deployment of Gogs through Docker can be said to be the most agile git warehouse building. Of course, I'll give the veteran a temperature, humidity
