Hi, hope some one can help me out trying to combine this two programs, I´m trying to make a stopwatch but the start buttons instead of being buttons I want to make them with FSR sensors,
I have already a program that works as a stopwatch but I need to change it to use the FSR and also because on the start is a pullup button (wich is good) but the stop is also a pullup button and while you keep pressing the time keeps running, and it should be a press button to just stop.
The First piece of code is the program that I use for the stopwatch, and the second is the program I use for the FSR sensor.
The goal is to combine the two programs, modify the stopwatch so instead of using regular buttons, use the FSR sensors, and make the start based on Pull up (so while you are standing the timer is not working) and the stop make it a press button but also with FSR, two different FSR that work differently.
Thanks in Advance, here is the code for the stopwatch
// StopWatch trying to change the way it starts and stops but using FSR
#include "LedControl.h"
LedControl lc = LedControl(12, 11, 10, 1);//Set up the Max7219 display pins
unsigned long previousMillis = 0;
unsigned long interval = 6;
const int buzzer = 6;// Defines the pin for the buzzer
byte estado = 0;// variable to avoid re-start of the timer before the other is on the race
byte pinsBut [] = { 7, 8, 9 };// Array for the start and finish button, Problem I have to change with FSR
#define N_BUT sizeof(pinsBut)
byte butState [N_BUT];
bool run = false; //States if the timmer is running or not
unsigned long msec0 = 0;
