Kit 10: Sparkling Pentagon L.E.D. Display

This circuit contains five light-emitting diodes arranged in the shape of a pentagon. A sparkling display is produced when the circuit is switched on as the l.e.d.s independently flash on and off. Different versions of the "Sparkling Pentagon" kit are available. Please choose the colour of the five l.e.d.s you would like in your kit. Choose either one l.e.d. of each colour (blue, green, pink, red, yellow) or choose five l.e.d.s of a single colour (either all blue, all green, all pink, all red or all yellow). Please have a look at a working version of the "Sparkling Pentagon" circuit on the Irby Electronics YouTube channel. When this circuit was tested, a set of Duracell Plus Power batteries was still producing a good light output after 90 hours of continuous use. The circuit is made on track board (approx. 6 cm x 2 cm) and requires 2 x AA batteries (not supplied). Precision soldering is ESSENTIAL for this kit so that solder on one track is not splashed across to an adjacent copper track. These tools are needed to make this kit (not supplied): small pliers for bending component leads and link wire, small wire cutters for cutting component leads and link wire, small, low power soldering iron, e.g. 15 watt, 18 watt or 25 watt. Please read the safety warning in the About Irby Electronics section before ordering a kit.
