I am teaching myself electronics. I designed this circuit to use a photoresistor to trigger a transistor when I hit the photoresistor with a laser pointer. On the Arduino side, I want it to look like a push button. That worked so I wanted to add an led as visual feed back that the laser is hitting the target.
The only way I could figure how to do this was to add a 2nd transistor. It works, but is this the correct way? I don't want to use another pin on the Arduino.
In the pic, pin 11 is supplying the 5V and pin 8 is reading the port.
