Hey guys,
I'm new to electronics and im basically trying to teach myself. I have a LM339 voltage comparator hooked up to a photocell and when it is hooked up to and LED for the output, The LED works fine. However, when i take the output and hook it up to a 1458 IC chip (this makes the LED fade on and off) the LED just rapidly blinks. What would my problem be?
The 1458 Chip works fine when hooked up to a 9v battery.
