Day 3: Switches, Relays, and Robots

After finishing my inventory sheet from yesterday, which was missing too many pieces to count...

I started with todays tasks.

We learned about switches and how they allow or deny the flow of current.

I connected 2 switches to an LED and some power, then i flipped one switch and then the other and each time the light turn on or off; this showed they were connected together and they interrupted the flow of power between the power supply and the LED.

We also learned about relays and their ability to switch power output to one LED or the other.

Once we got the LEDs lighting up back and forth and we got the "miniature noisemaker" integrated,

we moved on the the next part.

We started on our robots!

Since a lot of parts were missing from my toolbox, i did not get to finish everything and I had a hard time putting things together.

Eventually time ran out as it always does and i did not get to finish my robot, but i did get the main parts built.
