Servo Tool needed for Setup?

Using Arduino Programming Questions

i include a customized version pcRead(), included in the following, in almost all my projects to support testing of various aspects of the code as it developes and to support diagnostics. I'll add commands for functions specific to the application i'm working on

shouldn't the "tool" your searching for be part of your code?

// pcRead - debugging using serial monitor

const char version [] = "PcRead 240209a";

int debug = 0;

// -----------------------------------------------------------------------------
// process single character commands from the PC
#define MAX_CHAR  10
char s [MAX_CHAR] = {};

int  analogPin = 0;
