This kit consists of a circuit board measuring around 163 x 29mm which has provision for mounting 20 of the 14 X 7mm dual LED indicators on it to make a giant bargraph.

The LEDs are driven by a pair of cascaded LM3914/3915/3916 bargraph display drivers (the kit is supplied with LM3914 ICs), which can be switched to either dot or bar mode. The kit will run from any voltage of 5 volts or more, and can be used as an expanded scale meter for measuring 12 volt batteries (measures 10 to 15 volts), although it must be used in dot mode for this. Other uses include level measuring for water tanks, VU audio meters, and many other uses where a 10 segment dsplay just isn't enough.

The kit is designed so that the LEDs mount on the opposite side to the other components, so that you can mount the display flush up against a transparent window in equipment without the components being visible.

Currently available only with red LEDs.
