Thank you for one more time
A general question now..
lets say that we have 10 led in lm3914
We have select it to use it in dot mode and in step of 0.5 volts
0v= zero led
0.5v= 1st led open
1v = 1st led turns off and the second led goes on ...
Lets say now that we want to inspect 0,5v 1,5v 4v and 5 volt
For that we would use the 1st, 3d,8th and 10th led and we would not connect any leds to other pins of lm3914
But in this way when have 2volts input the led for 1,5v will go off until the 4v come and lm opens the 8th led..
can we made this in order to have always the led on before the next step we want to inspect??
i think that it can be done but i am not sure if i have to place a diode to the pins in order not damage the lm3914
