Relay-Driven LEDs
This post is a response to an exercise on the book “Make: Electronics”.
In this exercise, a DPDT relay and a SPST pushbutton are used to switch power between two LEDs. In its normal state, LED #1 is lit up. When the pushbutton is pressed, the relay is charged and switches the power from LED #1 to LED #2. Once the pushbutton is released, the relay goes back it its normal state, which causes the power to switch to LED #1.
