Hi guys,
Tonight I started looking into electronics as I want to do engineering at uni and thought it would be sensible to get some basic knowledge.
I found a beginner project to start on, the "atari punk console".
I'm using this schematics diagram
**broken link removed**
I understand the resistor and capacitor symbols and I know the square things are the dual timers but I'm having difficulty following the rest seen as I'm following no guide and this is literally all I'm working from with a tiny bit of prior knowledge from GCSE physics :-D
Could someone explain what the circles with '+' signs in them are. I thought they were batteries and the +9v suggests this too but seen as there's 5 of these icons on the diagram I thought it might point elsewhere. Also what is the GND symbol? I think it means the ground wire but I don't see where you'd ground it...
Another thing, the timer part has a part number "LM556N" but I can't find anywhere to buy it and instead I've found "NE556N". Would there be any difference between these?
Again, I'm sorry this is such a beginner thread. If there's an article or website someone could recommend to get started and familiarised with stuff that'd be great!
Thanks
