First, the previous figure: Accessories used: 1. Main Character: Raspberry Pi 2. secondary role: Infrared Detection 3. Miscellaneous: bread, DuPont wire, buzzer, led, resistor The infrared detection has three pins. The power supply at both ends and the signal output in the middle directly connect the signal to

PyImageSearch Gurus computer vision course. Our project will include home monitoring applications, such as motion detection and personnel tracking in the room. The following is a simple example of motion detection and tracking. at that time, I was making a call to move back and forth in the apartment.Install OpenCV an

Python and OpenCV installation tutorial on Raspberry Pi 2 or Raspberry Pi B +, pythonopencv My Raspberry Pi 2 just arrived yesterday. This guy looks cute. This guy has a 4-core MHz processor and 1 GB memory. You know,

Use Raspberry Pi to send push notifications to smartphones This project explains how to send push notifications from Raspberry Pi to iOS and Android devices. You only need to use a free push app. The main idea here is to use an electromagnetic sensor door to trigger information push events. When the electromagnetic doo

deployment are reflected in this, and the algorithm is copied directly to the Raspberry Pi to run debugging. Debugging process a little bit complex, the first effect is not good, patient adjustment, patience to change the algorithm, the effect will slowly come out.The effect of the motion let's look at the following content.third, follow -up demonstrationIndoor

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

FirstSome time ago, took a little time to do the number of children learning problems of the small programHomeDo a problem interface (topics are randomly generated every time, subtraction)To record a problem.Now the question is coming, how can we know at any time whether the homework is finished?It's too hard to refresh every time you open the title record page.So I made a Raspberry Pi + small LED light equ

Raspberry Pi has two audio output modes: hdmi and headphone interfaces. You can switch between the two modes at any time. If your HDMI monitor has a built-in speaker, the audio can be played through the HDMI interface. You can also switch to the headset interface to use the speaker of the headset or other headset interface to play the video. If your monitor requests support from the speaker, the sound is ou

Raspberry pi +opencv read camera Call the camera on the Raspberry Pi, read each frame in the video stream, and use the canny edge detection to extract the edges in each frame, the final effect is as follows: ReadVideo.cpp #include "opencv2/opencv.hpp" using namespace CV;
