Thanks for your last response. Today we wrote and tested: Run motor 1 forward at half speed. Monitor the microswitch at digital port 7. If the switch closes (Hit the wall!) then Stop the motor BEEP Run motor 1 backwards full speed for 1 second. Shut (...) (28 years ago, 10-Jan-97, to lugnet.robotics.handyboard)

Has anyone interfaced the HB to a PIC chip or other microcontroller without using the primary serial lines? I am wondering if maybe there was an I2C or SPI implementation done somewhere using digital outs. (28 years ago, 9-Jan-97, to lugnet.robotics.handyboard)
