So I'll start by saying that I understand if this topic has been broached before and I'm just missing it. For a big of background, I'm an aircraft mechanic, I know the bare minimum when it comes to electronics, well maybe a bit more then that. Though at my work we have specialists who come in for any of the really heavy lifting. So what I'm looking to get into is building a timer triggering device using a 555 chip, from what I can tell its one of the simpler/best ones to use for this purpose. One of the issues is that whenever I start reading up on it none of the explanations for the pins or how to build off of the chip. Any help in this regard would be a major help. Thanks.
