HI
I am setting up a circuit using LM3914 to drive 2 x 10 segment led bar graphs
I need to measure from 1 volt to 10 v with each led being .5 volt
I have attached a cuircuit. could some experts look at this circuit & tell me if this looks ok
I have put 2 pots in to adjust the lowest & the highest led turn on states
These are VR1 & Vr2, I have also added VR3 to adjust led brightness.
I have done this circuit like this so I can use it fo many different applications, eg but adjusting the low voltage to start at 4 & top out at 8 or 1 to 10 as i require this time.
As you will see I am not to electrics wise, but trying to learn more
Thanks in advance on any coments or sugestions.
