In this Instructable aimed at beginners in the magic of Arduino, I will show you how to make a simple circuit That requires no programming to build. I aimed this for kids like me, who are amazed with the world of computers and electronics and are eager to learn more.
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
Arduino Uno REV3 - 1
Breadboard - 1
Jumper Wires - 2
Pushbutton Switch - 1
LED (any color) - 1
Step 2: Start Assembly
Take a red Jumper wire and insert it into the hole labeled '3.3V'.
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'.
Step 3: Continue Assembly
Insert the other ends of both jumper wires as shown in the picture below.
Step 4: Add the Switch
Insert the switch into the breadboard exactly as in the picture below.
Step 5: Put in the LED
Insert the led as shown in the picture below. The longer pin should be connected to the other end of the switch across the gap in the bread board (Which is connected to positive, or 3.3V through the switch). The shorter end should connect to the black wire (Negative, or GND).
Step 6: Now, You Are Done.
Make sure the arduino is connected to a power source (The battery pack, or the USB to Serial cable), and press the button. The light should go on, but if it doesn't, either replace the LED, or check the steps and see if you did everything right. Good luck with Arduino!!
