Trigger Camera from GPIO Pins

Mon Apr 18, 2016 5:11 pm

Hi There,

I am new to using the raspberry pi and have purchased a Raspberry Pi 3 and a Pi NoIR camera for use in an aerial mapping project. I have the camera all set up and working using Raspbian. What i wanted to know is can i trigger the board to take a picture when a certain voltage is detected by one of the GPIO pins? I am using an APM 2.6 ( ... rview.html) which can be set to remote trigger a camera using 5V. Could this be adapted so it is connected to the raspberry pi to trigger the camera and if so how would i do this considering i have no experience with coding at all?

You can use a gpio pin as an input, high or low, and take a photo using raspistill or picamera using python.

Here's a python example using pir as inputs to take stills or video...
