Hi, I was wondering if anyone could help me with a problem i've got!
I've got a problem I need to solve, and basically I think I can almost solve it with a circuit using a LM3914. Trouble is I really dont know much about electronics and although I think I can almost get to grips with the circuit design I can't quite figure it out.
Could someone design this circuit for me please!?!?![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
I have a variable resistance that ranges from about 15ohms to 195ohms, and I need to light up the LEDs in a display like **broken link removed** along that resistance range. I was looking at using a LM3914 to do this.
So basically when the variable resistance is 195ohms 1 LED wants to be active and when the resistance is 15ohms all are lit. The whole thing wants to run off a 9V battery, and some trim adjustment for the min and max resistance would be nice.
If anyone could help I would be so gratefull! Thanks
