This ciruit will activate a motor for an adjustable amount of time, when a person or animal comes within range of the PIR detector.
Blox have +v and 0v terminal connections at either end so they can be chained together easily and reduce wiring. Solid core wire is used to connect the blox resulting in very little movement between boards.
Most circuits work from 4.5v to 18v but the ideal range is 9v to 12v - please check BLOX Index for details.
