3 Transistors no IC running LED chaser with speed controller

I show You how to make 3 Transistors no IC running LED light chaser with SPEED controller. This circuit using 3 small NPN Transistors without using any IC (Integrated Circuit). Share this video to help your friends or families to know about this. Subscribe Moristo Lekka Electronic for next video that might be useful for You. Component list: - 3 pcs NPN transistors; C/S9013 or BC547, You can use any other NPN transistor (but You have pay attention into EBC pin sositions). - 15 pcs or more 3v LED bulbs. - 4 pcs Elco 100uF/16v. - 4 pcs 4K7 Resistors. - 3 pcs 560 ohm Resistors. - 10K Potensiometer.
