- niwtsol 11mo agoThanks for sharing your fun project. Do you mind eli5 the logic of the circuit for someone unfamiliar with circuits?
- 2earth 11mo agoSure! The battery provides approx 6V - the timing circuit uses a 555 IC to create a pulsed signal. The combination of resistor and capacitor values determines the period of oscillation. Then, the output signal from this circuit is used to switch a transistor on and off. That makes/breaks a connection from the battery to the LED strings. I also added a switch to select between the red LED and Yellow LED strings. Will draw the final circuit if I get some time :)
