I just started building circuits and working with electronics about a month ago, so I am still very much a beginner. My latest project involves an IR LED and an IR receiver to act like a switch. When the IR receiver sees the IR LED, the circuit turns on a small 9v-12v electric motor, when the IR receiver sees nothing, the circuit turns off the motor. I found this website with a schematic of an IR circuit:
http://www.me.umn.edu/courses/me2011/robot/technotes/irbeam.html
The circuit on that website, though, is powering a single LED and I need it to power an electric motor, and I am sure there are many ways of doing this. In my eyes, I could either amplify where the original LED was so it has enough power to run the electric motor, or I could have a higher input voltage and restrict it down to 5v for the IR detector. What would be easier? Are there any other ways of doing this? Does anybody know of any other schematics that would be helpful?
