Hi, hopefully I've posted this in the right section. Please let me prefix this post with a disclaimer: I've never worked with circuits or electronics before. My interest is purely in scale modelling and I'm trying to use a 555 IC to get some blinking fibre optics as authentic as possible, as opposed to just using a 1hz blinking LED. I literally have no idea what I'm doing so please explain any answers like I'm a five year old.
I've followed this YouTube video exactly:
except that my components are:
R1: 39k ohm
R2: 2.7k ohm
R3: 230 ohm
Capacitor: 47 mF
This gives me a very short low time and a longer high time. I require this to be inverted. This is just for a single LED.
I'm sure this is fairly simple and I have googled it and found some suggestions that its quite simple for a single LED but I don't quite follow the explanations. If someone could refer to the circuit in the above video and tell me what to swap to where, that would be ideal.
Many thanks for your patience and help
