Change rhe amp meter for a 2k resistor.

I've spoken to the current in the mirror

But Billy, LittleLemon reference current is 4.24mA! 4.24mA @2kOhm would need a voltage of at least 8.5V! Its absolut correct to place an ampmeter to measure the mirror current. But if you do not like ampmeters then put at least a resistor which is within the possibilities of the current sink against 5V. E.g. 500 Ohm.

@hurz, thanks for the correction, I keep on falling for the simple stuff.
