real-time data acquisition and plotting using arduino and python is a powerful combination for creating interactive data visualization applications. this tutorial will guide you through the process of acquiring sensor data with arduino, sending it to your computer via serial communication, and plotting the data in real-time using python.
hardware and software requirements:
1. arduino board with a sensor (e.g., temperature sensor)
2. usb cable for connecting arduino to your computer
3. python (with pyserial and matplotlib libraries installed)
4. arduino ide
arduino setup:
1. connect your sensor to the arduino board.
2. upload the following arduino code to read sensor data and send it over the serial port:
python setup:
1. install the pyserial and matplotlib libraries using pip:
2. use the following python code to receive data from arduino and plot it in real-time:
running the code:
1. connect your arduino to your computer via usb.
2. upload the arduino code to your board.
3. run the python code and adjust the com port and plot settings as needed.
final notes:
make sure to adjust the delay in the arduino code to match your desired data acquisition rate.
you can customize the plot appearance and add additional features like axis labels and legends.
experiment with different sensors and data visualization techniques to create interactive and insightful real-time applications.
feel free to ask if you have any questions or need further clarification!
