Kyrio 5PCS LED Electronic Lights Kits Red Blue Dual-Color DIY Flashing Light Kit Components NE555 CD4017 Strobe Electronic Suit

• This is a very interesting circuit for simulating the visual effects of warning lights, blue and red lights flash alternately according to the pulse respectively.
• Red flashing lights and blue flashing lights are in separately board, can move off from stamp hole to increase the distance or separate installation to other places.
• The working voltage is DC9V-12V. There is no IC socket in kits. User can weld IC on PCB Directly.
• This kit is simple to assemble, suitable for electronics enthusiasts and students to practice. Design optimized for training, it adopts 1.6mm electric board and nice layout of the components.
• 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.

1. This suite adopts simulation light circuit made with NE555 and CD4017, the blue LED and red LED flashed alternately according to the pulse. 2. The multivibrator composed of NE555 will have a certain frequency of oscillation signal send to CD4017 decimal counter/pulse distributor, in order to count. 3. 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. 4. 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. 5. Red flashing light and blue flashing light form a board separately, connected with the main board through the stamp hole. 6. 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. 7. Please pay attention to the direction of LED when installing, especially the direction of L11 and L12. 8. The R2 and R3 controls with the brightness of light, you can change it appropriately , the range is 10-100 ohm. Installation note: The kit uses red and blue light-emitting diodes. The blue LED has a higher turn-on voltage than the red LED. Therefore, the red LEDs are connected in series of four, and the blue LEDs are connected in series of three. Pay attention to this first. If the color is reversed, a higher voltage is required to light up. Package Including: 5 * NE555 CD4017 LED Electronic
