This is a simple one, it designed to recognize movement and then snap photos.
It has a li-ion battery and an easy USB charging cirquit using the TP4056 module.
So go ahead, get us a grate wildlife photos...
Step 1: List :
220 ohm Resistor
TP4056 li-ion charger module
ON/OFF tuggle switch
Step 2: Diagram
Li-ion battery connected to the TP4056 module wich gives power to the PIR module.
The PIR module output 5v when sensing movement.
The PIR module output is connected through a resistor to an optocupler that closes the circuit of the camera remote connections.
Easy isn't it ?
Step 3: Camera
The camera is pre focused and pre set for the photo, then set the trap and wait for your greate wildlife photo.
