The L293E is not a replacement for the L293D. The D suffix means "Diode" and it includes the snubber diode to prevent the chip from being destroyed by inductive loads. --Chuck (27 years ago, 1-Oct-97, to lugnet.robotics.handyboard)

Hi Rob, Based on the messages you're getting, I'm guessing you're running freeware IC under windows. If you run under DOS, it should work great. The problem is that, since freeware IC doesn't call Windows serial communications routines, it will (...) (27 years ago, 1-Oct-97, to lugnet.robotics.handyboard)

Mar, I've never seen a caster as small as you describe, but I have seen something that might work. I use a "captured ball" bearing instead of a caster on my robot, and it works really well (no swivelling needed to change direction). I got these at a (...)
