Hello all,
I'm not sure if this is the right area to post this to or not.
I've been working with my Mindsotrm set of late and have created a program
that will control and detect when two trains cross at a crosstrack. My
program will stop once track and allow the other one to go thru before
starting up the "stopped" train. Everything works fine (program,, track
circuit isolation, trains, etc.) The only problem I'm have is that the light
sensors I'm using CAN NOT DETECT the light from a LEGO Light brick. I
initally started using a flash light but a flashlight is non-LEGO and I wanted
a pure LEGO solution. I have used a diode and created a small cicuirut to
supply it with power, but this again is a non-LEGO solution. Has anyone out
there been messing around with these light sensors?
Thanks
Ahui Herrera
