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 know about this.

Component list:
- 3pcs NPN transistors; C/S9013 or BC547, You can use any other NPN transistor (but You have pay attention into EBC pin positions).
- 15 pcs or more 3v LED bulbs.
- 4 pcs Elco 100uF/16v.
- 4 pcs 4K7 Resistors.
- 3pcs 560 ohm resistors.
- 10K Potensiometer.
LED Chaser Circuit is a circuit in which the LEDs lights one by one for a period of time and the cycle repeats giving the running light appearance.
Here, I will show you three different ways to make a LED Chaser Circuit:
1. 4017 IC
2. 555 Timer IC
3. Only transistors
You can also control the speed of all three circuits by varying the resistance.
