Evghenii has developed a system that automates the process of recognising cars and opening gates based on who they are. The system, which uses a Raspberry Pi, an IP camera and some relays plus a mixture of Python (including OpenCV), shell scripting (I can feel a headache building already) and Telegram messaging has the following principles of operation:
The car drives up to the gates.
Camera reads the car plate numbers.
Checks the read number with the database; if it finds one, then it opens the gate and lets the car pass.
Each car at the gates is photographed, then a photo is sent to the Telegram application with the car plate number and its status.
Telegram bot has the ability to open and close the gates, take a current photo and add an unknown car to the database.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
