This is a simple Inverter Window Comparator Circuit Diagram ICl-c
 functions as a non inverting comparator, and ICl-a operates as an 
inverting comparator. Potentiometer Rl and fixed resistors R2 and R3 
form a divider chain that delivers slightly different voltages to the 
two comparators. These voltages define the upper and lower limits of the
 circuit`s switching window, which can be changed easily by varying R2 
and R3. The LED glows only when the input voltage falls within the 
window region.
