Hello, everyone. This is my first electronics project, and all I'm
trying to do is get a light to blink. I looked up schematics on about
10 different websites, all which have failed.
I have a 9 volt battery, the proper resistors, capacitors, etc. It's
driving me nuts.
Generally, the problem is all the schematics call for pin 1 to be
connected to ground, and pin 8 connected to V+. I don't know exactly
what this means, so I connect pin 1 to the negative current, and pin 8
to positive current. When I do this, I feel like it's shorting out or
something, because nothing else on the breadboard (like an LED in
parralel to the 555 circuitry) will work, and the battery starts to get
really hot.
But besides that, I do everything exactly as in the schematics, and
everytime nothing works.
I'm getting really frustrated at this thing because I set up everything
exactly as in the schematics, plug it in, and nothing happens. I would
really appreciate your help, as I've pretty much exausted every 555
timer website on the net for help.
Thanks for your help,
