I am using this camera: https://a.co/d/eq1SfY9 and want to record a video at 2 fps and start a motor the moment it starts recording. I have the code for the video but I've noticed that trying the camera starts recording about four seconds after the motor starts. This is the code I used to verify that. When I run that code, the video ends up being around 6-7 seconds long. Is there any way to wait until the camera is recording to run the motor? I mean something along the lines of this:
So that the motor runs for 10 seconds and the video is also exactly 10 seconds. Thanks.
Code:
