Timer creation

Projects General Guidance

Hey Guys,

I have been trying to create a fitness timer that can be set through the options displayed

For example,

An LCD can say,

What is your gender(2 options Given) --> What type of workout(2 options Aerobic or anaerobic) --> what is your age(4 Ranges are given) --> What is your weight (4 Ranges are given)

Approximately 56 possibilities of times can be given.

In order to do this:

I would like to set up four pushbuttons that will respond to the user's input.

How do I write a code for this (All I require is the code with just one or two if statement configuration, no need to do all of the combinations).

Please help me, this is a project for my University course.

Also, I am using a SparkFun LCD with RX, GN, and VD, I do not require specific commands with specific plug-in points.

Thank you (means a lot if you help me)

Here is the sample code for one option:

#include <SoftwareSerial.h>

#define txPin 2

SoftwareSerial LCD = SoftwareSerial(0, txPin);
// since the LCD does not send data back to the Arduino, we should only define the txPin
const int LCDdelay=10; // conservative, 2 actually works
int TestSwitchPin = 5;
int TestSwitchPin2= 6;

// wbp: goto with row & column
void lcdPosition(int row, int col) {
LCD.write(0xFE); //command flag
LCD.write((col + row*64 + 128)); //position
delay(LCDdelay);
}
void clearLCD(){
LCD.write(0xFE); //command flag
LCD.write(0x01); //clear command.
delay(LCDdelay);
}
void backlightOn() { //turns on the backlight
LCD.write(0x7C); //command flag for backlight stuff
LCD.write(157); //light level.
delay(LCDdelay);
}
void backlightOff(){ //turns off the backlight
LCD.write(0x7C); //command flag for backlight stuff
LCD.write(128); //light level for off.
delay(LCDdelay);
}
void serCommand(){ //a general function to call the command flag for issuing all other commands
LCD.write(0xFE);
}

void setup()
{
pinMode(TestSwitchPin, INPUT_PULLUP);
pinMode(txPin, OUTPUT);
LCD.begin(9600);
clearLCD();
lcdPosition(0,0);
LCD.print("hello World");
}

void loop()
{
if(digitalRead(TestSwitchPin) == LOW)
{
LCD.begin(9600);
clearLCD();
lcdPosition(0,0);
LCD.print("hello World");
}
if(digitalRead(TestSwitchPin) == LOW)
{
LCD.begin(9600);
clearLCD();
lcdPosition(0,0);
LCD.print("hello no");
if(digitalRead(TestSwitchPin2) == HIGH && (TestSwitchPin) == LOW)
{
LCD.begin(9600);
clearLCD();
lcdPosition(0,0);
LCD.print("hello what");
}
}
}

And yes, I will give cresit for those who have helped me

this is a project for my University course.

In your final report, will you give appropriate credit to the Arduino forum members who helped you?

3

Start with the Debounce example, so that you know how to handle buttons. Then advance to more sophisticated items.

4

You will need at least a fifth button - correction. And a sixth - reset. Probably more.

Anyway, do look into how to handle and read a button. Build your UI around that.
