Colour

Available kits contain one l.e.d of a single colour: either blue, green, red or white.


This circuit is constructed on track board and contains one light-emitting diode which is switched on and off at a rate determined by the integrated circuit and associated components. The rate of flashing on and off can be changed by the variable resistor.

More details about this circuit and its construction are available here.
Precision soldering is needed for this kit to avoid solder on one copper track coming into contact with an adjacent copper track.

Project 9:  Darkness Detector

Skill level:     * *     Intermediate

Battery required:  1 x PP3 (not supplied in kit)

Cost of kit:  £5.30

Standard kit contains one white l.e.d.

Standard kit contains one l.e.d. of each colour: green and red.
Alternative kits contain two l.e.d.s of a single colour: either blue, green, red or white.


This circuit is constructed on track board and contains two light-emitting diodes which flash alternately on and off at a rate determined by the integrated circuit and its associated components.  The rate of flashing on

and off can be changed by the variable resistor.

More details about this circuit and its construction are available here.
Precision soldering is needed for this kit to avoid solder on one copper track coming into contact with an adjacent copper track. 

The easiest project to make on foam board. The "surprise" about this circuit is that such an ordinary-looking light-emitting diode can produce such a colourful display. The l.e.d. changes colour over about 30 seconds and then the cycle repeats. For a really spectacular display, place a cut-glass container such as a tumbler or a tea light holder over the l.e.d. 

More details about this circuit and its construction are available here. See Project 7 for an alternative version of this circuit constructed on track board.

Soldering is recommended for this kit but the joints in the circuit could be made by twisting wires together and then squeezing the connection with pliers.
