As shown, the circuit consists of a dual-core 556 and the light emitting tube. The left half of the IC (556 1/2) composition R1, R2, C1, etc. frequency of about 2Hz multivibrat
or; the right half of the IC (556 1/2) composition and R4, R5, C2 and so on about 0.5 the multivibrator Hz. The output of 5,9 feet respectively drive the red, green light-emitting diode, resulting in red, orange, green three colors that blink of glory.
