I am using a phototransistor ( nte 3037 ) to input (max 10hz) to the lm2917-14 and then have the output range from 0-5 vdc to supply to a lm3914 for display.
This is my first project and I can not figure out what I am doing wrong. I have been searching and reading but still cannot get it to work. I am hoping someone can help me figure this out.

ps I e-mailed National and they replied that the chips are old and I should use a MCU instead because it is newer and easier.
