Hey Everyone,
Im new to electronics and i have a project that i am working on using a quad voltage comparator and a 1458 dual op amp IC chip.
Well im basically trying to get a photocell circuit (lm339) to turn on and off the 1458 circuit to make LED's fade on and off.
Both circuits work perfectly when working by themselves but when i put them together taking the cathode and anode of the with positive and negative of the 1458 the LED blinks rapidly and im trying to figure out why it wont work.
Sry if i confused anybody
