Thank you for any help at all.
Probably not, but I'm going to do it, anyway.
int pin0 = 0;
int pin1 = 1;
Two numbered variables. Fine.
int force = analogRead(pin0); // analog reading from the Force sense resistor
int force1 = analogRead(pin1); // analog reading from the Force1 sense resistor
WTF happened to the numbering?
const char *msg = "1";
const char *ms = "2";
Ditto.
const int led = 3;
const int led1 = 4;
Ditto.
Serial.print(buf[i]);
Not going to tell us, huh. Fine. Be that way.
Do you know that the LEDs are wired correctly? Do you KNOW that you are sending anything? If you do, do you know how long the LED will stay on? I'm guessing that the answer to this one is no. Your indenting does not help.
