Day 3: Introduction to Switch and Relays (Video)

Experiment: Switch and Relay

In this image you can see my breadboard and on it is a several wires, an LED light, resistor, and two switches. Each switch has three terminals which are the outer terminals and the central terminal. The switch alternates from one outer terminal to center to the alternative terminal to center. At all times the center is involved.  

On our setup I learn of the positive and negative ports on the breadboard and with my previous knowledge of circuits I was able to understand the current flow in this system. We first drag power to the first switch on the right to its central terminal and then place the second switch next to the first and continue the circuit by connecting the second switches central terminal to the resister then LED light in order to not burn out the light with too much power.

A relay is the small box next to the LED lights. Our relays have a total of 10 pins, five on each side. Inside the relays there is a coil that when electricity run through it it creates a magnetic force. Which pull a metallic lever in the relay and that is how the relay alternated the power flow.  

In this image you can see that when I physically push the button and allow power to go through the circuit the LED light switched from Red to Green. This visual demonstrates the function of the delay . 

This was the experiment of an Oscillating Relay. What we did is add a small capacitor which will temporally consume the power and charge which will slow the oscillation. This will resemble the car "right" or "left" turn signals that we all use.
