Project idea

[Asghar Amir]

Which mini project is best using op-amp..help me out with this please

 

[Harald Kapp]

A simple amplifier?

 

[kellys_eye]

High/low temperature alarm, high/low voltage alarm? In fact any 'alarm' where a difference can be measured - using the op-amp as a comparator.

Best to avoid using a '741 op-amp for any project where only a low-voltage single-polarity supply is available.

How about a simple oscillator?
