A/D转换：读入电位器抽头处的电压值V0，并进行判断比较。当电压0V<V0<1V时，LED3点亮；当电压1V<V0<2V时，LED3、LED4点亮；电压2V<V0<3V时，LED3、LED4、LED5点亮；当电压3V<V0<4V时，LED3、LED4、LED5、LED6点亮；当电压4V<V0<5V时，LED3、LED4、LED5、LED6、LED7点亮。
A/D conversion: read into the potentiometer voltage at the tap V0, and to determine the comparison. LED3, LED4 light voltage 2V <V0 <3V, LED3, LED4, LED5 light when the voltage 3V <V0 <2V, when the voltage is 3V <V0 < LED4, LED5, LED6 and LED6 are lit when the voltage is 4V <V0 <5V, and the LED3, LED4, LED5, (2016-10-22, Visual Basic.NET, 1KB, 下载1次)
实现四路抢答，电路具有第一抢答信号的鉴别和锁存功能,在主持人将复位按钮按下后开始抢答，并用EDA实训仪上的八段数码管显示抢答者的序号，同时扬声器发出“嘟嘟”的响声，并维持3秒钟，此时电路自锁，不再接受其他选手的抢答信号。
一个计分电路，每组在开始时设置为100分，抢答后由主持人计分，答对一次加10分，答错一次减10分。
设计一个犯规电路，对提前抢答和超时抢答者鸣喇叭示警，并显示犯规的组别序号。
Achieve four answer.
The circuit have a first answer signal to identify and latch function, after the moderator began to answer the reset button is pressed, and EDA training with eight digital tube display on the meter s serial number answer, while speaker beep sound, and maintained for 3 seconds, and the circuit self-locking, no longer accept the other players answer signal.
A scoring circuit, each set of 100 points at the start, scoring after the answer by the moderator, the correct answer to a 10 points, got it wrong once by 10 points.
Design a foul circuit for advance Responder and Responder were honking warning timeout and display group numbers foul.
