摘要
以AVR单片机ATmega8L为核心,提出了一种智能LED紧急刹车灯的软硬件设计方案。通过A/D转换电路将采集到的MMA1260加速度传感器信号输入单片机,并与门限值(设定值)相比较,控制LED车灯的闪烁,以此警示后面的司机,避免发生追尾事故。
The hardware and software of the intelligent Led emergency stop light are designed based on ATmega8L MCU.The signals collected by MMA1260 acceleration sensor are inputted in MCU through the A/D converter circuit,and compared with the threshold (set of)to control the Scintillation of LED lights, so this can warn the driver behind to avoid rear-end accidents.
