  • I fail to see the humor in that.

    Are you suggesting he should go out and buy another controller with fewer pins, just to play with this experiment?

    Maybe a smaller breadboard too? And shorter wires?

  • A basic but useful example on how to use a microchip.

  • you could run also this USB system for programming and serial emulation through the USB in Linux. Research on google about SanUSB linux. There is also folders in 4shared.

  • what is the code you typed in?

  • you could run a GLCD with USB connection to PC with that !

  • Nice. The 18F4550 is a bit of overkill for something like this (a 555 timer would do). I'm guessing this is one of a series of tutorials, and more advanced projects follow? The '4550 can actually run Microchip's TCP/IP stack and serve simple web pages...

  • Perhaps you can show us how to do it with a 10 pin SOIC? Me personally, I'm going to redo it using the PIC16F946 which is a 64 pin monster with built in LCD controller. How's that sound?

  • You could use this setup for that but it's a bit overkill. It would be better to include that in the ecological code of your robot.

    To OP - great project, keep up the good work, but I suggest using an electronic tweaker tool rather than a metal screwdriver in the future when adjust trim pots and caps, especially around high voltage or lots of amps (not the case here but it's a good habit to get into).
