Simple hands detector maked using cvzone for this scope (see OpenCV and mediapipe for more information) and firmata protocol for communication with microcontroller Arduino.
The result of this detection results in the hardware turning on/off of 5 led diodes.
From Arduino IDE go to File > Examples > Firmata > StandardFirmata.ino. Once you open the code you need to connect the Arduino microcontroller and load the StandardFirmata.ino sketch.
Now open your Terminal and clone this repository with the following command:
git clone https://github.com/AntonioBerna/hands-leds.git
Now use cd hands-leds/ to access the directory, make virtual environment and start it with the following commands:
virtualenv venv
source venv/bin/activate
Good! Now install the requirements for using project with the following commands:
pip install cvzone
pip install pyfirmata
pip install mediapipe
or
pip install -r requirements.txt
Perfect! Now that everything is ready you need to build the electrical circuit with the 5 led diodes. Here is what the schematic looks like:
Finally, we can send the project into execution with the following command:
python src/main.py
NOTE: Remember to check if your Arduino is connected to a USB port!
Don't worry if you forgot to connect your Arduino, my program will notify you with the following message:
No Arduino port found.
If all goes well after running python src/main.py you should see the following window:
Now all you need to do is select the port on which Arduino is connected (from the drop-down menu provided) and click on the Open Camera button to display the following outputs:
NOTE: This project is fully compatible with macOS and I am working on compatibility with Linux 🔨
