Basically i wana trigger it 2 turn on a motor for 10
sec..the problem tht i have is jst 2 give the trigger input a pulse without using a push button.so i just need a circuit that can give 1 pulse when activated 2 trigger the timer.i tried a inverter logic gate to trigger the 555? but the timer stayed on and didnt go off.is it more clearer nw?thanx
I dnt have the resources of scanning rite now as im using my mobile 2 place threads but basically pin 2 on the 555 is connected 2 ground and the not gate is joint 2 it,hope u understand what im sayin.thanx
Try this schematic which includes the necessary switch debounce to ensure your 555 is triggered correctly.........do not be scared of it
