DIY Motion Activated Wildlife Camera Arduino Project. 12:39 pm August 30, 2018 By Julian Horsey. ... It sleeps in low power mode until, activated by the motion sensor, it takes a picture.

The BOM on [Jeremy S Cook]’s build is extremely short – just a PIR sensor and an optoisolator, with a battery, a plug for the camera’s remote jack, and a 3D-printed bracket.

All you need is an Arduino, a motion sensor, a few wires and headers, and the code provided at the site below. Hit the link to see step-by-step instructions on how to put it together.

For this project, you’ll need to write a program that tells the Arduino to trigger the camera and flash when it detects a sound. 2. Piezoelectric Sensor: This sensor will act as your sound detector.
