    A little bit faster now... a little bit faster now...



    Compare that to the stock D2-6 robot: https://www.youtube.com/watch?v=IEMWil1kzzg

    And easy Bluetooth control using a free Android app named "Blue Control": https://www.youtube.com/watch?v=3npXpqmQuwI

    Reverting to the $5 line follower kits. These are comparator-controlled, not programmable. Still fun to do some hardware hacking. I repositioned the photocells, cross-wired the motors and did my "drive straight" mod and now they seek/follow light.

    Two different implementations shown.

    Late to the party here, but did I miss where this was posted? Would like to see it if available.

    Didn't really make a schematic of my Picaxe board, just free formed it to plug into the headers on the D2-6 board, replacing the Chinese micro. Pinouts attached.

    Hi,

    Looks a very good value kit and a great idea to picaxe it.

    Still, I am puzzled by the low supply voltage (3V). Is it powered by AA batteries? Motors should be rated for 1.5V-2V.

    The battery is a lipo 14500 3.7volt
