Week 2: Solderless Breadboards

In lab, we learned how to make our very first solderless 'Breadboards'. But what is a 'Breadboard' and how does it relate to circuit boards? In the video link below, you can see visually how in the early days, people who would experiment with making a circuit for application using a 'Breadboard' and the name stuck when the created the actually connection board that we known of today.

Collin's Lab: The REAL Breadboard

In this post, I'll show you how we made our own boards for use, and how I experimented with the different resistors on hand.

What you'll need:

One Solderless Beadboard Kit; Some of the items pictured here were not used in this particle construction but will be used in a later project. For this project what you'll need is the:
  • Solderless Breadboard
  • Two 10mm LED lights
  • 9 Volt battery with Connector
  • Breadboard Jumpers
  • Connecting wires
  • 2 resistors
  • 1 KMG 50 V Resistor (To interrupt the resistors)
  • 1 chip

(In this kit, it came with a Arduino, small circuit chip, and alligator clips but we put those to the side)

Diagram to Follow:

First, by following the connector diagram, attach your chip, resistors, lights, and battery cable onto the breadboard first. You should feel something grip onto each connection very lightly as you push them into the slots so that they connect to the ground of the Breadboard:

When putting it together, it's easier to start with these components first before putting in the wires.

Then, connect the wires, and follow the diagram exactly or else it's not going to light up:

Then finally, you connect the battery to see if you placed all the slots into the right holes:

Once you celebrate that you have a working Breadboard, you can experiment with different resistors to get different blinking effects with your lights like I did and have way too much fun with that magic:

These resistors/capacitors interrupts the flow of electricity to the LED lights and causes them to blink intermittenly at different speeds. The ones with a higher voltage blink faster, and the ones with a lower voltage blink so slow you think that you broke a connection somewhere on the first try:

And then this guy in my class gave me this one, and my board lost it's fucking mind:

It was so fast my phone's camera capture rate couldn't even keep up with it.
