Breadboard. Wow.

Who would've thought that a tiny board with tiny little holes could be so intimidating? And possibly the most fun I've had for a long time? This is my adventure of figuring out the breadboard, circuits, and this little activity known as soldering.

I decided to make a power jack to power up the breadboard, which requires soldering. I had no idea that soldering was about melting solder to connect metals...if it wasn't for some good advice I would have put the soldering iron directly onto the wire!


Once the soldering was done, I had a power jack:

It took me a while to get started, but ultimately, the concept is logical and simple. A circuit is needed for electricity to work. A breadboard is a tool to create such a circuit. Once I figured out how to create a circuit with the voltage regulator in place, and successfully placed the correct wires into the correct spots...I finally succeeded in getting the LED to light up!

One great thing about building a circuit is that it is nothing abstract about it: if you do something wrong, the circuit is broken and it won't work. After many trials and errors, I did manage to get a few variations of the lights and switches to function.

and finally, I added the motor. Here is a video of me completing a circuit that activates both the motor and the LED.

Transistors... Honestly, I have no idea what I did. I successfully built some circuits involving a transistor as I followed the diagrams in the labs, but I have no understanding of what I actually did.

As I tried to use the variable resistor, I managed to slow it down momentarily, but failed to make the motor stop. Then...the motor wire broke...
