I'm new (and novice) in electronics. I came to seek your knowledge to see if someone can help me with a very basic circuit.
It is a 555 chip, which should light a LED (for about 1/2 second) every hour. I managed to make the circuit diagram with a well known software.
My question is that I do not know what values to put the resistors and / or capacitors to achieve this frequency of light or flash. Actually, this triggers a parallel circuit (so I need the trigger every 1 hour). I guess there must be some calculations to obtain these values, but what I've seen online I find very difficult to understand. I am not a student of electronics, only an amateur trying to learn as well as realize a project. Now the circuit works, but not in the desired frequency flash lighting (every hour a little flash).
PS: Attached image of the schematic. Sorry for possible faults in the text, I used Google translator.
PS: I think this is an astable and oscillator circuit... but I'm not sure.
