We will present and demonstrate a stroboscope system using four colors of LEDs. The LED driver circuit consists of the basic logic circuit by which NOT is NOR and D-FF, etc.. An experimental setup consists of the stroboscope as a light source and a two-blade propeller which is mounted on a DC motor.
The two-blade propeller is rotated, and observed that was illuminated by the stroboscope. Since along with the blinking frequency of the LED, the observation color of the rotating propeller is changed, it can be expected to be a studying material which stimulates the children’s intellectual curiosity.
