Offer simple lighting console to "Melodic the indicator" described in "Radio", 1992, № 8, p. 12-15. It contains just ten LEDs LB and five resistors. The detector, as completed the device will play the melody with the dynamic lighting effect.
To make the console easy: in melodic motion detector has a counter clock pulses DD3 (Fig. 1 in the above article), the findings of which (14, 12, 9, 8, 11) and to output +5V supply connected circuit of two series included LEDs and current limiting resistor (see diagram). LEDs form the screen of the CDS, which, depending on the imagination of the Amateur, can to perform as a line, circle or rectangle on the front panel the motion detector. SDU operates during the time of the alarm sound.
In the prefix applicable LEDs ALA, ALA, ALB or ALBM. Possible to use LEDs with different light color, for example, HL1 and HL2 - red, ALA, ALA, ALB or ALBM; HL3 and HL4 - green, ALV, ALUM, ALG or ALGM; HL5 and HL6 - yellow, OLD, ALDM, or ARE ALAM etc.
