PySerialTransfer is pip-installable and cross-platform compatible. You can interface Python with Arduinos via USB serial easily using the compatible libraries: pySerialTransfer and SerialTransfer.h. # if the `q` key was pressed, break from the loop # extract the confidence (i.e., probability) associated with the # pass the blob through the network and obtain the detections and # grab the frame dimensions and convert it to a blobīlob = (cv2.resize(frame, (300, 300)), 1.0, # grab the frame from the threaded video stream and resize it # loop over the frames from the video stream # initialize the video stream and allow the cammera sensor to warmup

#PYTHON SERIAL VS PYSERIAL CODE#
(excuse my code neatness I haven’t cleaned it up yet) # USAGE From what I’ve seen nobody else has had this issue and I’m completely confused why this is happening. I know that this seems like a baud rate issue but I double checked and every Arduino was set to 9600 and the python program was too. All that shows up is random ascii characters. I hooked up the rx and tx lines of the Arduino to another Arduino and opened up the serial monitor of the second one so I could make sure that the right info is coming through. The only problem is that it doesn’t seem to want to control the servo. After figuring out the usage, I implemented it and I can see that the Arduino is receiving the data because of the RX led. After some research, I found that you can send serial data from python running on a laptop to an Arduino with PySerial. My simple Arduino code takes any value from 0 to 400 (the centerX value range) and maps it from 0 to 180 to control a servo. My facial detection python works great and I am able to calculate the center point of the face and store it in centerX and centerY variables. My goal in this project is to use openCV’s facial detection to track a face in a video and output the location to an Arduino to control a servo. Now I’m trying to get my feet wet in some python. I’ve been creating projects with Arduino for years now and have had a lot of fun.
