1. Description

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.
supply power : 9-12V

Please note:

Blinker constructor. The assembled device simulates the signals of flashing beacons of special equipment. And it’s not just switching red-blue, namely, a couple of blue cycles, then a couple of short red ones, etc. The board is made on a getinax, but the conductive layer holds well and allows even a beginner to solder (with possible overheating and even allows a one-time replacement of parts, no longer dare). In the kit are all the details, LEDs, even for a couple of extra pieces. The designations on the board are detailed, it allows you to assemble a flasher even without a circuit, although it is clearly not enough to understand the principle of operation in the kit. The assembled device starts working immediately, without adjustment and selection of elements. In general, the kit can be recommended as a training tool for practicing soldering skills for beginners.
