Good evening all. I am doing project to turn off led after a fixed time of 10 seconds. I implemented ckt using ic555. After 10 seconds the led goes off. The problem is I dont want the led to go off if I give another trigger within 10 seconds. I want the led to keep glowing if I give trigger within 10 seconds. Please suggest for the same. Thank you
using IC555 it is not possible.
u should use any programmable device with memory like micro controller
because it can keep track of number of trigger applied and increase LED ON time as per number of triggers
