| Oct 11, 2016 at 14:04 | comment | added | Makoto | instructables.com/id/… Thats a simple 555 implementation. However you will probably need a transistor on the output to drive the load. I don't think that the 555 can drive that much current without blowing | |
| Oct 11, 2016 at 6:14 | comment | added | Pedery | Hi, and thanks for your answer. Would you mind sharing examples on how I can achieve #2 (with a 555 timer) or #3? Preferably with a link to a simple diagram or something so that I can play with my breadboard. I tried #1 with a (too large) potentiometer, but the fan seemed to either be switched on or off. Later this week I'll get a shipment of more suitable potentiometers, and can test this option then. | |
