LM3914 LED Display Driver Kit #1
This is the LM3914 LED Display Driver IC Design Kit #1. It includes 1 piece of the very popular National Semiconductor LM3914N Dot/Bar Display Driver IC in a DIP-18 package and enough support components to build some exciting circuits. The LM3914 is a monolithic integrated circuit that senses analog voltage levels and drives 10 LEDs, providing a linear analog display. A single pin changes the display from a moving dot to a bar graph. The circuit contains its own adjustable reference and accurate 10-step voltage divider. The buffer drives 10 individual comparators referenced to the precision divider. Versatility was designed into the LM3914 so that controller, visual alarm, and expanded scale functions are easily added on to the display system. The circuit can drive LEDs of many colors, or low-current incandescent lamps. Many LM3914s can be chained to form displays of 20 to over 100 segments. Both ends of the voltage divider are externally available so that 2 drivers can be made into a zero-center meter. The LM3914 is very easy to apply as an analog meter circuit. If the 1 resistor is a pot, it becomes the LED brightness control. Various novel displays are possible. The datasheet can be found at .
This kit also includes various quantities of 1/4 Watt Carbon Film Resistors, Transistors, Ceramic, Aluminum & Tantalum Capacitors, Signal & Power Diodes, LEDs, various Trimpots, Microphones, Speaker, and some Electronic Hardware to interface to the real world.
To further help with your circuit development, you also get a 162 plated-thru hole PCB and some IC sockets. This PCB has 4 mounting holes, is 1.1" x 2.0", and is double-sided. With these parts, you can make numerous circuits such as Battery Monitors, Audio Spectrum Analyzers, and many more. Search the web for incredible circuits to build. The Datasheets and Application Notes for the ICs and Transistors, along with hundreds of others, are located at . We supply the parts, you supply the ingenuity. You get the following:
