This suite adopts simulation light circuit made with NE555 and CD4017
the blue LED and red LED flashed alternately according to the pulse.
The multivibrator composed of NE555 will have a certain frequency of oscillation signal
send to CD4017 decimal counter/pulse distributor,in order to count. When the 1,3,5
pulses arrive Q0,Q2,Q4 output high level in turn,blue LED flashes 3 times,Q5,Q7,Q9
output high level in turn.Red LED flashes 3 times,blue LED flashes again when
11,13,15 pulses come,blue and red LED flashes alternately circulatory, so as to like
the alarm lamp.Change the RP1 size can change the oscillation period, thus
changing the LED shining speed, the whole circuit DC9-12V can be worked.
Red flashing light and blue flashing light form a board separately, connected with the
main board through the stamp hole.If you need to install to other place separately or
increase the distance,you should cut off through the stamp hole,then connect with the
mother board by two wires.
Please pay attention to the direction of LED when installing,especially the direction of
L11 and L12.The R2 and R3 controls with the brightness of light,you can change it appropriately ,the range is 10-100 ohm.
