How to create a small (UPX compressed) program, that still contains enough information to generate a useful stack trace in case of an error.
This is an improved version of my first Light Seeking Robot.
I’ve been attempting to control an LCD using my brand new Arduino and a 74HC595N shift register, in which I failed (for now). I also tried the MCP23016 pin expander, which I got working after quite some experimentation. I even wrote a library for it!
To get me started, both on this blog and with my brand new Arduino Uno, I’ve built this Light Seeking Robot and I have documented it here for your entertainment.
