A novel initiative towards the digital image processing technique by the application of histogram of oriented gradients (HOG) feature descriptor using the OpenCV library coded with the High-level programming language Python, booted with the help of Raspberry Pi microcontroller fitted with a RaspiCam to capture moving images of objects passing under it has been presented in this Lawrence Library's Raspberry Pi gate counter project - carylwyatt/gate-counter. Before you start setting up the software, make sure that you have My thinking was that this one wire is positive when the door bell is pushed, then the Raspberry Pi will complete the circuit connecting it to ground. I have captured the IR receiver signals using an oscilloscope. FYI, since I asked the question, a colleague of mine did implement that frequency counter with external reference using a RPi-pico, albeit not using If I press the button connected to one of my Raspberry Pi units it successfully uses MQTT to send a signal to the lockbox and that Pi unit (after 10 seconds which is quite the Using the Raspberry Pi. I would probably run your code as a daemon with say an open socket that I could connect to, from some data acquisition code being run by cron, to get the count The door is motion-activated, and will. 3V Do not connect 5V to the PI inputs/Outputs, it will damage the PI.
