Tech Club

Tech Club A few weeks back I visited a club where we used LEDs and circuit boards. When I was there, we started with a brief introduction of what are LEDs. Apparently LED stands for “Light Emitting”. The use for LED are illumination and indication. That we decided that we use the LEDs for indications. On the table, they placed a few small red, blue and green LEDs along with resistors and something called a “breadboard”. The breadboard had many holes just like bread, hence the name “breadboard”. I also noticed the LEDs had two small connectors attached at the bottom. This kind of reminded me of the LEDs flashing in my phone showing me notifications and what not. We started connecting wires and the blubs on the boards. Some places that were connected made the LEDs EXTREMELY bright but some made the light dim and faded out. However I was warn if there was too much voltage going through the LEDs it permanently damage them and can be prevented with some resistance wires. Moments later we use a computer program that integrates the use of LEDs sort like giving data out. For example, if an action is triggered or completed then one of the designated lights will light up or shut off depending on what choose it to be. I think I had better understanding of how LEDs works and how I can incorporate this into some coding in some other classes.
