I am using a 555 timer in the monostable configuration, which means that when I send a pulse to the trigger pin, the falling edge will make the 555 generate a high pulse on the output for some time. However, if the pulse on the trigger pin is held down for a time longer that the output pulse, the output will remain high until the trigger goes up again.
How can I make it to end the pulse independently of the pulse duration on the trigger input? I have found this solution:
But it seems to not work to me because I'm not using a button, I am using a voltage directly connected.
