Product overview

• Create a running light effect with three flashing channels
• Connect up to two LEDs per channel for a maximum of six LEDs
• Easy and fun to solder with five parts
• Requires a 3-6V power supply (not included)

What can I do with this kit?
Build a sequence of running lights from one flashing LED up to six, and run them in a light effect with this kit. The board has three output channels, and you can use as many or as few as you need. You will need an external 3-6V power supply to power this kit. At 3V you can light one LED, and a 6V you can light two. The lights flash approximately three times per second (3 Hz) and have a duty cycle of 76ms. With just five parts, this kit is great for anyone from beginners to experts.

What can I learn about with this solder kit?
Practice soldering and learn about electronics and circuits with this running light solder kit, which uses a resistor, capacitors and LEDs. The circuit uses capacitors to decide which LEDs light at any given moment. Learn how the components are connected in a circuit and get practical experience in soldering them. The kit can be used with 1-2V LEDs with an operating current of 10-20mA. You can use larger 2.5-3.5V LEDs, but they must be run off a 6V power supply and only one LED per channel. This kit requires a soldering iron and solder and may require wire cutters.

How easy is this kit to solder?
Easy to solder, this kit is great for beginners learning about electronics. You can also combine this kit with others and create your own projects. You could build an enclosure (not included) for the circuit to protect the electronics, or build it into a display or model. This kit runs off a DC 3-6V power supply (not included).

Rated 5 out of 5 by from Alternating warning lights I've wired this little alternating flasher unit up to 2 sets of 2 red LEDs and one 6V buzzer and it works a treat as warning device for an air flow monitor.

Does this drive LEDs with constant current? If so, what current? I would like to use it with superbright LEDs.
Asked by: tom
Depending on the operating voltage altogether 1 - 10 light-emitting diodes may be connected. The module has 2 outputs which are switched on alternately (at option flasher or alternating flasher operation). Depending on the operating voltage one or several LEDs can be connected in series at each output (do not connect in parallel). At 6 V/DC 2 LEDs can be connected per output at maximum, at 9 V/DC 3 each at maximum and at 12 V/DC 5 LEDs per output at maximum. This applies to red LEDs with an operating voltage of 1.6 V. If LEDs of different colour and higher operating voltages are used, the number of pieces which may be connected decreases accordingly. The flasher has a built-in current limiting at approx. 60 - 80 mA. Modern 5 mm LEDs are designed to impulse currents of approx. 60 - 100 mA at 50% continuous duty and can be connected directly. Older LEDs and special LEDs (e.g. miniature-LEDs) do not endure those currents. In these cases an appropriate protective resistor must be connected in series of the light-emitting diodes. Please pay attention to the correct polarity of the light-emitting diodes: the longer lead of the LED is “plus” and must be connected with the IC at “+” according to the drawing. If the module is employed as flasher, one of both “L” – outputs of the module remains unattached. The drawing indicates the module as alternating flasher for 2 light-emitting diodes.

Is this really "6V OR 12V" or will it run on "6V TO 12V"? (i.e. will it run off a PP3)
Asked by: John
The system is designed to run from any voltage between 6v and 12v, the higher the voltage the more LEDs can be illuminated.
