Traffic Signal Light Circuit Using BC547 Transistor | Simple Electronics Project
In this video, I'll show you a very simple traffic signal light circuit using three BC547 transistors and other simple components.This circuit will flash three LEDs. The time interval can be changed by adjusting the capacitors. More power capacitor decrease speed and less power capacitor increases the speeds.
