About this product
The LM3914N is a monolithic analog-to-LED driver that reads an input voltage and lights up to 10 LEDs as a bar graph or a moving dot. LED current is regulated and programmable, so individual current-limiting resistors are not needed, and the display can be expanded to 100 steps.

Do I need a resistor for each LED?
No individual series resistors are needed because LED current is regulated and set by the chip's programming network. Check the datasheet for the external programming components.
How do I set the voltage range the display measures?
The internal 1.2 V reference together with the RHI and RLO pins, using a resistor divider, sets the full-scale and zero-scale voltages that the input is compared against. Verify the divider values in the datasheet for your range.
