Brown, red, orange, yellow, green, blue and purple, flashing seven colors can improve students interests in study of electronics technology and help them comprehend the fast development in the science field. #This circuit uses one NPN transistor, two PNP transistors, resistors and capacitors to form a three phases multivibrator. When the circuit is operating, NPN transistor is off while PNP transistors are on and. R1, R3, R5 and C1, C2, C3 determine speed of cycling. This circuit uses three colors LED. When G or R conducts, LED shows green or red color. When G and R conduct at the same time, LED shows orange color. Therefore, LED lights up as a sequence that is red, green, orange. This circuit operates at 6V. It requires four 1.5V batteries.
