A Relay Oscillator
This post is a response to an exercise on the book “Make: Electronics”.
In this exercise, a DPDT relay and a capacitor are used to switch power between two LEDs. In its normal state, both LEDs are off since the pushbutton is not activated. Once the pushbutton is pressed, power is sent to the capacitor. While the capacitor ‘charges up’, the relay is in its normal state, which causes LED #1 light up. Once the capacitor is ‘charged up’, it sends out ‘stored’ energy, which causes the relay to alter state, therefor powering LED #2.
