Lm3914n Pinout. 1 solder the lm3914 ic on the veroboard. 2 solder the ve terminal of the 3v piezo buzzer with pin 10 of the ic.
After that solder the ve terminals of the nine leds with pin 1 18 17 16 15 14 13 12 and pin 11 of the lm3914 ic. Pin configuration circuit working and applications in the year 1980 national semiconductor was launched the ic lm3914 and is still obtainable from texas instruments. The lm3915 is a monolytthic ic designed to sense analogue voltage signals and produce an incremental or sequential logic switching across its 10 output.
The ic provides a decimal output by lighting the necessary led based on the value of input voltage.
To give power to the lm3914 we connect 5v of power to the pin 3 which is the v pin. The ic provides a decimal output by lighting the necessary led based on the value of input voltage. The following typical application illustrates adjusting of the reference to a desired value and proper grounding for accurate operation and avoiding oscillations.
