该电路图包括有开关K1,第一电阻R1,第二电阻R2,第三电阻R3,电容C1,LED（Light Emitting Diode,发光二极管） L1,第一针脚P1,第二针脚P2以及提供3.3V电压的电源V1.其中,所述的第一针脚P1,第一电阻R1,开关K1,第三电阻R3,LED L1,第二针脚P2依次进行串联,所述的第二电阻R2与所述的电容C1并联连接,该并联连接的一端连接到所述的第一针脚P1及第一电阻R1之间连线,另一端接地.所述的电源V1连接到开关K1与第三电阻R3之间的连线.所述的LED L1的正极连接到第三电阻R3,负极连接到第二针脚P2.所述的电容C1正极连接到所述的第一针脚P1及第一电阻R1之间连线,负极接地.所述的开关K1还与所述的输入设备2中一输入按键连接,当按下该输入设备2中的该相应的输入按键时,开关K1合上,第一针脚P1端电平高,从而产生硬件中断.当系统发送高电平给第二针脚P2时,由于LED L1另一端通过电阻R3连接有电源V1,该LED L1所处的电路接通,该LED L1有电流通过,故此时该LED L1亮；当系统发送低电平给第二针脚P2时,该LED L1中没有电流通过,故此时该LED L1熄灭；当系统发送高低间断电平给第二针脚P2时,该LED L1中有间断电流通过,故此时该LED L1闪烁.

The electric circuit's diagram includes the switch K1,the first electric resistance R1,the second electric resistance R2,the third electric resistance R3,the electric capacity C1,the LED( the Light Emitting Diode,give out light the diode) L1,the first needle feet P1,the second needle feet P2 and provide the power supply V1 of the 3.3 V electric voltage.Among them,say the first needle feet P1,the first electric resistance R1,the switch K1,the third electric resistance R3,the LED L1,the second needle feet P2 carries on establish one by one in order,say the second electric resistance R2 and the electric capacity C1 say merges the conjunction,shoulding merge the conjunction on carrying to link say the first needle feet P1 passes one an on-line of the electric resistance R1,another on carrying to connect the ground.The power supply V1 say connect the switch K1 with the on-line between the third electric resistance R3.The cathode of the LED L1 say link the third electric resistance R3,the anode link the second needle feet P2.The electric capacity C1 cathode say link say the first needle feet P1 passes one an on-line of the electric resistance R1,the anode connects the ground.The switch K1 say return with the input device say 2 medium an importation key conjunction,be press that input device 2 the importation key that should correspond mediumly,the switch K1 close,the first needle feet P1 carry electricity even and high,thus produce the hardware interruption.When the system sends out the high electricity even give the second needle feet P2,because of the LED L1 another on carrying to have the power supply V1 through the electric resistance R3 conjunction,the LED's L1 connects the electric circuit of the place,the LED's L1 has the electric current to pass,for this reason hour the LED's L1 is bright;When the system sends out the low electricity even give the second needle feet P2,in the LED's L1 there is no electric current pass,the LED's L1 of for this reason hour put out;When the system send out high and low interrupted the electricity even give the second needle feet P2,in the LED's L1 interrupteding the electric current to pass,for this reason hour the LED's L1 flicker.
