Hi guys. Beginner here.
Made my 1st 555 delay timer on my breadboard and its all good.
Just wondering about the reset pin (4). Right now i have it connected to +Vcc.
If i move it to ground then the 555 goes off but as soon as i pull the pin 4 out of the ground (not even connected to +V) the 555 carries on and the LED comes on instantly without delay. Is that normal. Operation? Or the reset pin when grounded should restart the timer?
Thanks
