LM3915N Display IC Dengan Harga Minimal 100rb https://shopee.co.id/product/38187023... What is the LM3915 IC? The LM3915 datasheet specifies that the IC is a monolithic integrated circuit that senses analog voltage levels and drives ten LEDs, LCDs or vacuum fluorescent displays, providing a logarithmic 3 dB/step analog display. One pin changes the display from a bar graph to a moving dot display. LED current drive is regulated and programmable, eliminating the need for current limiting resistors. The whole display system can operate from a single supply as low as 3V or as high as 25V.
