Its my first time of using optoIsolator. I have connected a PIC MCU to Control the External DC motor through it.
The problem is; I am not able to control the Base current ! I don't know the Current Gain in OptoIsolator, i have somehow used transistors in the past.
So I have calculated the input current via --> [(Input-1.7(led))/130] = 25.3mA.
Now i am not able to guess the current at output Emitter of OptoIsolator. It gives me very less current (0.03mA) at the output. Its too low.
I have attached the Snapshot of the circuit herwith.
