Greetings.
I am brand spanking new to the world of electronics, and could not be more excited! I wanted to get my feet wet with a very simple project, but I have already hit a wall. I am trying a simple signal conversion with a mercury switch and a Schmitt trigger inverter (SN74LS14N). If I hook the switch to an led and resistor and close the switch, I get light. However, when I connect pin 1 of the IC to the switch and output pin 2 to a led, its a no go for led number 2. I have not yet mastered the art of reading a data sheet, but if I had to guess, I am missing some kind of voltage threshold. I have tried various resistors to join the switch to pin 1, but no luck.
I apologize for my lack of proper terminology. I hope this question is understandable. I literally received my first soldering iron five days ago and have several beginners books on order. I just couldnt wait to power something up
Thank you for your time, and thank you all for this fantastic website.
