1. I made a simple L.E.D. that can be switched with a push button. This instructable is the first in my series of arduino guides and tutorials.
2. I made this device by taking all the parts included in the 'What you will need' step and brainstormed (very quickly, because this is very simple) a way to make the circuit function properly and make a simple layout on the breadboard.
3. I made this L.E.D. device in my room at my house, on my desk that i use for everything from homework to chemistry to electronics work, not unlike what I did in this instructable.
4. I learned while making this, and many of my other electronic gadgets that usually, if you think you built a circuit perfectly on your breadboard and it's not working, then you need to check every single place in the circuit where a part goes, and see if you messed up a small part of the design, and then, if it still doesn't work, one of your parts is likely to be defective, or your power supply is not on/ not working. And, if all of these problems don't seem to be getting solved, keep on trying as hard as you can to build it successfully, and never, ever give up on science. Ever.
Step 1: What You Will Need
Breadboard - 1
Jumper Wires - 2
Pushbutton Switch - 1
LED (any color) - 1
Step 2: Start Assembly
Then, take a black jumper wire and insert it into the first hole labeled 'GND', which is the second hole to the right of '3.3V'.
