The Blinker module turns a direct current input into a square wave output, allowing you to make LEDs blink and Buzzers beep. This circuit blinker has a green LED flashing in time with the output and a red LED to indicate if power is connected the wrong way. You can change the blinking rate by turning the LED blinker wheel!
