Hey guys,
I am a physicist, not micro electronics experience whatsoever, and my adviser said that I should put together a circuit that could make a solenoid (24V) open with a USB 5V signal. This solenoid will serve as a shutter for a laser we are using to calibrate an instrument we have.
After a few hours on the computer I found that the Optocoupler 4N25 would be the way to go. Actually I thought it would be straight forward, and went ahead and bought the thing.
I got it three days ago, and after almost 24 hours of restless work, I still haven't make the circuit to work.
I have a breadboard, a couple of multimeters, a computer and a dc regulated power supply. It would be no problem at all for me to shut down a USB port and turn it on again to send the signal.
here is the datasheet: http://www.vishay.com/docs/83725/4n25.pdf
What should I do? I am trying to organize like this image attached... Am I doing something wrong?
Can someone show me how to do it... I am really desperate!...
