I need help. i have made a 555 timer from this site http://www.kpsec.freeuk.com/projects/timer.htm
i used a lever switch to replace the switch there. i configure my lever switch as NC . i found out the 555 timer trigger my load (e.g LED) for 2 sec and off is fine which i thought off the 555 timer too BUT because my switch is in NO that doesn't off the 555 timer circuit which depleted my battery source really fast. HELP!!!
My switch need to be in NO. how can i solve this problem.
*i have been in stress in making this and think the circuit is wrong. and remaking it and also think the voltage is insufficient... i feel so dumb to find out actually the 555 timer circuit is continually depleting my battery. i really need HELP.
