急救车与交通灯)(1)南北与东西方向,每个方面由红黄绿三个灯控制(2)南北向: 红(30秒),黄(5秒),绿(25秒) 东西向: 红(35秒),黄(5秒),绿(25秒) 上述基本参数可以根据实际情况自行调整,灯的变化规律与实际路口规律相同,绿灯在最后5秒钟时,黄灯亮,然后红灯亮,不允许两个方面同时亮绿灯。(3)绿灯的时间显示在数码管上进行显示。(4)可以通过一个开关控制,当开关信号为0时,整个交通灯全灭提高要求:(1)设计一个紧急控制开关信号,当紧急开关信号为1时,两个方向的灯全为红灯。紧急开关撤消后,按照开关按下之前的状态继续运行(其参数要保存)。(2)设计一个夜间行车开关,当开关按下后,两个方向都只有黄灯闪烁,其它灯熄灭。(3)设计两个方向的亮时时间可调。-emergency vehicles and traffic lights) (1) North and South and east-west direction, each with three yellow-green from red lights control (2) to the north and south : red (30 seconds), yellow (5 seconds), Green (25 seconds) to things : red (35 seconds), yellow (5 seconds) Green (25 seconds) above basic parameters can be adjusted to the actual situation, the light changes with the actual law of the same intersection, the green light in the final five seconds, the yellow light is on, and then a red light, bright, not two fronts simultaneously bright green. (3) the green light at the time displayed on the digital display control. (4) can be controlled by a

l298调 速 程 序 常规的接法是这样的,EnableA接PWM信号,Input1输入正反控制信号, Input2是Input1经过反相以后的信号。L298的电平是与TTL电路相兼容的,一般是超过2.5V就为高电平。假如Input1为高电平时电机正转,那么低电平时就是反转,PWM信号控制电机的转速。
_________________
-l298 procedures conventional speed connection that is the case, EnableA then PWM signal, Input1 input positive and negative control signals, Input2 is Input1 through after RP signal. L298 level is compatible with TTL circuits, and is generally more than 2.5V for the high. If Input1 is high when the motor is transferred, then that is when low-level inversion, PWM signal to control motor speed. _________________
