5 Led Chaser Circuit Using Transistor. There are ways to create a pcb at home but they require the use of chemicals and normally the final result is not perfect and is a tedious work to create several identical ones. The heart of this circuit is the shape of this pcb.
5 leds are blinking as shown in this video gif. You can connect more leds as this sequence by adding some more transistors. Without this diodes the led won t be fully turned off if we operate this circuit at 6v or higher voltage power supply.
Off course you can omit these diodes if you want to operate this circuit using 3v batteries lower the resistors r1 r3 and r5 if you do this.

We can also say that this is a led running effect chaser circuit this is an easy circuit and it can easily construct at home by even who beginner in this field.
