DIY SEQUENTIAL LIGHTS SERIAL

Connect the LEDs with the current limiting resistors of 150 ohms to the outputs of the IC 4017 in serial order of its output pins as - 3,2,4,7,10,1,5,6,9,11.Next wire the IC 4017 and interconnect the two IC with the help of the diagram,.

DO NOT forget to connect the unused inputs of the gates either to a logic 1 or a logic 0.

Complete the oscillator section first, by connecting the 100 k and the 4.7uf capacitor to the appropriate pins of the IC 4049 as per the given diagram,.

Begin the assembly of the LED running light circuit by fitting the two IC s somewhere in the middle of the board, leaving some space in between them.

The construction procedure is done through the following simple steps:

LED (color as per your choice) - 10 nos.

General purpose board - 5" / 3" - 1 no.

You will need the following parts to construct the circuit of this LED running light: Another good oscillator configuration may be tried using IC 4060. Out of the six gates in this CMOS IC, only two have been used to get the required frequency output that drives the IC 4017. For the present circuit I have used IC 4049 to get a square wave signal. There are unlimited options to get an oscillator configuration using IC s like 741, 4093, 555, transistor mutivibrators etc.

Without an oscillator clock pulses cannot be generated, hence it is also an important and integral part of this circuit.

An IC 4049 Provides Clocking for the Circuit This is exactly how the present circuit of the LED running light functions. You may also like to refer to my article on the construction of a combination lock where the same feature of the IC has been exploited.īy connecting a group of LED s to the outputs of the IC 4017 and applying a clock pulse at pin 14, the LED s can be illuminated sequentially, giving a running or chasing effect. This property of the IC can be utilized to construct numerous different electronic projects. There we have discussed that when a clock signal is applied to pin 14 of IC 4017, its outputs change state sequentially with every rising edge of the clock pulse. You have already learnt quite a bit regarding the pin designation of this IC in one of my previous articles. The heart of the circuit of this LED running light is the CMOS IC 4017. (Black with Blue Stripe) In the image below it shows the two wires optionally soldered together.A Simple CMOS IC 4017 Circuit for an LED Running or Chasing Effect No additional repair wire is needed.ġ) To ground the puddle lamp you can use the supplied red Scotch Lock and crimp the short Black wire from the puddle light bulb to the Mirror Defroster ground wire. The puddle lamp wire includes the terminal wire end for 12v plug and play installation. NOTE : You will need to remove your door panels and VAG COM to add this function on your vehicle. Simply remove those and reverse the steps above to put back your mirror. Otherwise, if you will not be doing the puddle lamps you won’t need the included bulb socket and wires. If your LEDs are not coming on, turn off hazards and check to make sure the PINs are aligned to your connector.ħ) If you choose to wire up the optional Puddle Lights, continue to the Puddle Lamp write up below and do not close up your mirror just yet. Align the connector and ensure the pins go into the connector. 6) Plug connector back into the turn signal socket and test.
