Easy made. You want to connect this to 12v replace 330 Ohm
to1 KOhm. Can use 100K without 500K volume controller.
OP AMP
Knight Rider Circuit
to1 KOhm. Can use 100K without 500K volume controller.
10 Minute Timer Circuit
Can change time using volume controller and 220u capacitor.
Output is depend on your input voltage.
Eg :- 12v Input - 12v Output
Change your 330Ohm resistor as your input voltage.OP AMP
very useful. Best of luck.
