# Is there such 555 timer circuit?

I was wondering if there is a simple 555 Timer circuit, or even simple transistors circuit, that has a HIGH output for 1sec, 2sec, or more seconds when I trigger the input switch and will remain HIGH till the specific time is done then it will go LOW. Knowing that when I trigger the input switch like 5 times quickly and repeatedly this shouldn't impact/interrupt the output at all, which means when I hit the input switch a multiple times the output will go HIGH for 3 seconds or whatever the time and will turn off once time cycle is done, and will go HIGH again for another 3 seconds if I'm still hitting the switch!

Sample timing diagram for OP to edit:

• Welcome to EE.SE. We use timing diagrams rather than words to show how the circuit should respond to the trigger signal. I've given you a sample ASCII diagram in your question. Please edit this to show all the possible input conditions and output conditions for each. Use multiple diagrams if required. Note four spaces at the start of each line to be formatted in fixed-width font. What happens if the trigger remains on? Sep 6 '18 at 23:16
• That sounds cool Transistor, I hope I can use the timing diagram to demonstrate the circuit. I will try! Thanks

• hmmm it looks like you already made it Transistor, just noticed that! Thats exactly what my whole paragraph is talking about, thats amazing man! Thanks!
