I'm not a newcomer to electronics but I'm a newcomer to ICs and thought I'd try a 555 timer to flash a LED.
I've tried this over and over again - the LED just comes on and stays on.
I've recently recreated the circuit in a simulation program and the same happens.
Please- what stupid thing am I doing wrong?
