Amazing project! You can also connect or tap a magnetic Reed switch on the base and emitter terminals. A small magnet or a refrigerator magnet will close the switch, once you remove the magnet near the Reed switch will open to trigger the device...

در حالت بیکاری، اتلاف جریان داریم و خودبخود باتری توسط مقاومت سرراهش خالی میشود. بدرد نمیخورد
