I have been reading non stop about LM3914's and have some questions. I have read through the datasheet a whole lot and still fail to understand things. My plan is to have 20 LED's in 4 rows so 80 LED's. The LED's will be powered by 12 volts and the range for the bar graph will be 0 to 5V. I am looking for the 4 rows to go up together as the 5 volt signal increases.
So the things I am looking to do is to make this thing as bright as possible! Can I get some push in the right direction? Basically which particular LED's would be the most beneficial to use? Also, would I just be needing to cascade two LM3914's together and then split to 0-5volt signal to each set of two? Ideas?
