I would like to make a simple circuit, where the a potentiometer controls a 0 – 10 second on-time.
If the potentiometer is set to min, the on time should be 0 seconds. If the potentiometer is maxed out the circuit should be on 10 seconds.
I was thinking of using an Arduino, but that would be overkill for such an application. And too expensive as well. Maybe a 555 timer would be an option?
All help is appreciated!
- Circuit must be 5V or 12V DC
- The object to turn on is a 12V car lightbulb. (some advice about a relay?)
- Has to be cheaper than using an Arduino
