Hey all I am relatively new to the world of electronics. I have been learning about the different modes of the 555 timer chip because I would like to incorporate it into an upcoming project. I made a circuit and did the calculation so that once a button was pushed, an led would stay on for 5 seconds and then go off (a one shot timer). Everything worked ok accept I noticed that when hooked the battery up to the bread board (my last step of the build) the LED would turn on stay on for 5 seconds then shut off. Is there a way to wire it so that when power is initially applied to the circuit it doesn’t trigger the timer? In other words the only thing I want to trigger the chip is a push of the button, nothing else! please let me know if this make sense. Thanks!
