woa7 said:how do you set up a lm3914, i need one to show 4-5v and another to show 2.5-3v, do you just use 2 pots to adjust the low and high settings to where you need them?
woa7 said:so i adjust r1 to 1.2 then apply half the voltage i want the meter to display, then adjust r4 until the 5th led lights?
im new to electronics, so when i see "Vout = Vref (1 + R2/R1) + Iadj R2" that doesnt help so if you could give me a detailed example of how to calculate the resistor values that would help out a lot, like an example of how calculate the resistors needed for it to show 1-2v
