Lm3914 Schaltungen. It starts with a simple explanation of how it works how to use the formulas for a basic bar graph display and how to transpose the formulas to calculate unknown values. The chip senses the measuring input voltage as a parameter and compares it with reference every time the voltage crosses the certain part of reference the corresponding led glows.
Da lm3914 eine strombegrenzung für die leds anbietet sind vorwiderstände nicht notwendig. Simple led battery monitor created with lm3914 in the video i use a dc motor for stressing the battery. Substituted for the l e d s the lm3914 can be used to control up to ten functions via a two wire link.
El circuito integrado lm3914 consta de una serie de amplificadores operacionales en modo comparador con los cuales se activara una escala de leds en pasos que dependerá del voltaje de referencia ajustado en el circuito integrado.
