PURPOSE: Couple roses are provided to let LED inside the roses being blinked by human body resistance. CONSTITUTION: Couple roses comprise a touch circuit which uses human body resistance, LED inserted in the roses, a capacitor, a transistor(C1815), and a semiconductor device Dot/Bar Display Driver. The capacitor prevents the unnecessary noises from entering into a base of the transistor. The current passed through the capacitor is amplified at the base of the transistor, and the resistance outputs the amplified current. The resistance interlinked to a number 10 pin of the semiconductor device, resistance, and the capacitor let LED to be blinked. The LED inside the roses are blinked by resistance of the human body if the couple holds one hand together and press touch points of the roses using the other hand. |
