My idea: Taking still photos when triggered by a pulse rate sensor and saving it onto a SD card. The device is to be worn on a dog.
1) First of all, is the arduino uno powerful enough for my application?
2) Any recommendations on the camera module to use? Something that takes decent picture.
PS: Trying to replicate something similar to this. http://heartography.nikon-asia.com/#how-it-works
Would appreciate some inputs. Thanks!
