Hello again,
Yes, op amps like the 741 present another problem for using in circuits like this. The input voltage for linear operation has to be significantly higher than the minus supply voltage and significantly lower than the positive supply voltage. The different could be as much as 8 volts in some units, so at least a plus and minus 15 volt supply is usually recommended.
The LM358 on the other hand is a little more easy to get along with. It's inputs will work down to the minus supply rail, and up to the positive supply rail less 1.5 volts.
That's a better op amp to start with, although it does not have built in offset adjustment pins like the 741 does.
