hello! recently started playing st7565 lcd screen using adafruit's library - still uses char arrays strings. plan screen use output debug info, problem trying build 1 long string out of variables have strewn about. i've been kind of bad @ concat'ing strings together, char arrays whole other beast of frustration me. here's i'm trying do: i have 3 variables - var1, var2, var3 what want send display "variable 1: (var1)  variable 2: (var2)  variable 3: (var3)" char array. any tips? quote i have 3 variables - var1, var2, var3 and types of variables are..?

hello! this first code. know little of other languages mel , as2, here, there tricks gotta used to. the simple code: the idea send number(id) via serial, , arduino recognize integer , work around number. by far have this code: [select] int id = 0; void setup(){  serial.begin(9600); } void loop(){     id = serial.read() - '0';       for(int i=0; i<id ; i++){     serial.print(i);     serial.print(", id: ");     serial.println(id,dec);     } } which prints, if send 8: 0, id: 8 1, id: 8 2, id: 8 3, id: 8 4, id: 8 5, id: 8 6, id: 8 7, id: 8 i can, then, use <id> integer , ok. but when send number greater 1 digit(12, 145...), messes of course. in short, i'd know how convert data incoming via serial integer.  if send (12, "12", not "1" + "2"). there other issues thought easier solve, syntax won't let me move further. lots of old examples including libraries out of date, , little lost... thanks in ...
