As my first project I want to have an LED shine onto a PhotoTransistor. when the beam is broken something happens.
I imagine using a standard LED and PHOTO TRANSISTOR would be problematic as there would be pollution from other light sources.
On the other hand there appears to be loads out there for infrared receivers and transmitters. this scares me slightly as the projects that use these require oscilliation for the LED transmitter (and receiver??).
So, do I build the LED\Photo transistor or try and tackle the infrared stuff?
Could I build the infrared circuits without an oscillator (continually on?)
Sorry to be thick.
