comparator

a comparator is a device that compares two voltages or currents and outputs a digital signal indicating which is larger.

this op amp takes two voltages 9v or 6v and 
outputs either 5v or 0v
output is high if   + > -
output is low if   - > +
output is low if   + = -

use the switches to redirect the inputs to the comparator

interestingly I found that if I removed the volt meter the circuit failed   a  10k resistor  fixed that

this hopefully will become a component in my to be built 555 circuit
