I am sitting here in my seat, cackling, because I started with a breadboard and assorted components, followed the instructions, and now I have an LED that lights up when you push a button.

It didn't break! It worked! I got the polarity correct all around! And, let me repeat, it didn't break!

I am so stoked you all have no idea~


Simple circuit with a battery, resistor, push button, LED:

Simple circuit with the button pushed. LED is lit up!

ETA: ahhahah and I just reread the instructions, and realized that they actually gave which color resistor to use. I tried to calculate it on my own, and ended up using a 10k resistor rather than a 1k resistor. Ooops. Still lit up, like the photo shows, but (not shown) after changing resistors, the light is brighter.

Ahahahaha omg breadboards. The bane of my existence in physics days! Go you! So awesome you're having so much fun with it!

Like Perl, there is more than one way to do it, but having fun is the right way!

Oh fond memories for me (I used to do this with my dad).

Congrats, Fu!

Heh! My first time in a college EE lab I'd bought the wrong wire kit for the class, so I was sitting there cutting and stripping wires to fit the breadboard, and when I put the first simple logic circuit together it didn't work at all as advertised. I checked everything twice, mystified the TA, and then gave up and started to take it apart. At which point I noticed the smashed pin under the chip...
