Again, we successful modified the circuit with adding a red LED and a 300 ohm resistor which is in series with it..Yosh ^^
After the circuit is switched on, the LED will light up.
By adding this LED, we can know the circuit is running well or not without using multimeter.
Also, by adding the LED, the output voltage and current is decrease, become -5.071V and current become 5.718mA.

After modified the circuit ^^
