[futurekit]7 LED CIRCULAR CHASING LIGHT (FK1223) [상품코드: 1160255]
This kit is an AstableMultivibration oscillator principle which can generate 3 steps of frequency by 3 transistors. The FK1223 controls 6 LEDs’runningin a couple of LEDs in a circular pattern correlatively, with remaining an LED light up in the center without generating frequency.
[futurekit]2 LED NIGHT LIGHT (FK1224) [상품코드: 1160256]
This kit is designed on the principle of ambient light falling on the light sensitive junction of the photo transistor. The FK1224 is able to automatically turn ON the light in night time. On the other hand, it can turn OFF the light in day time. The 2 LEDs work when the circuit turns ON and OFF in sequence. In addition, the sensitivity value of the photo transistor is able to be adjusted by trimmer potentiometer 500K.
