Hi,
I need to calculate the resistance values of the circuit shown.
The BJT is a BC337-40 and has a β of 250 and Vce = 0.7V and Vbe = 1.2V
The opto-coupler has an average forward current of 80mA.
Input is from a computer minimum of 2.5V. I've chosen to make values with 3V.
I feel like it is simple but I just can't make the values match up when I calculate resistances.
