OPB704 Line Sensor


I have received questions regarding the line sensor that I'm using on my mini sumo bot. Here I will post the schematic and pictures of the board.

Thank-You, LMR

I just wanted to say thank you a lot LMR for providing me a chance to discover the wonders of robotics and electronics. Before I found this website all I knew was how to change the batteries for a searchlight and now I have found my true hobby, my field of studies and, hopefully, future employment.

Few months ago I was given a chance to publish my project in an expo of youngster scientists and was even shown on a reportage about it on a national television.

R2 Like (Phase 1 Video Added)

I went ahead and added a video of this little start here's robots performance. Now I just have to find some time to tweak him. I think these should be my adjustments.

  • Modify code so that he scans his entire width of his body for obstacles.
  • Fix the third leg on the bottom so that he is more level and not looking upward.
  • Add LED turn signals.
  • Add a light sensor to the bottom front so I that he can be placed on a desk or counter and know when he hits the edge.
  • Add a speaker/buzzer/ect just for fun.

Note: You can follow some projects some of the time, but you cannot follow all the projects all the time.
