Modified Typhon sketch

No1Daemon · Apr 30, 2015

Hi all

I am building a cheap full spectrum led for my sump light and am looking for a Typhon sketch modified to use an lcd shield with all buttons connected to one analog pin of the arduino.

Didn't realise this would be such a mission. I see plenty of references to people who have done it successfully but cannot find the modified code anywhere.

Does someone have it that can send it to me?
I am working on doing it myself but would prefer not to reinvent the wheel if possible.

Thanks

How is the arduino going to work out which button is pressed if they are all connected to the same pin?

You use analogread and connect them to 1 pin and the arduino reads a different voltage for each so it knows which button is which by the value from 0 to 1023

You say all buttons connected to one pin. Do you mean each button is connected to a different pin? If not, I still don't understand how the arduino is meant to know which button?

Or do you mean each button will have a different voltage and the intent is only the highest pressed at any one moment is read?

Its okay. I have got the code working.
There is an internal resistor divider in the arduino similar to one you would build yourself so that each button has a difference resistance.
The arduino reads the pin and gets a different number for each button that relates to voltage read.
There is a code you can run that will give you the number for each button on the one pin and you then set up your arduino to use those numbers instead of reading a high or low on each digital pin a button is connected to.
Very handy and saves you digital pins.

Neat solution.

You mean the circuit you have the buttons on has the resistors, surely? The arduino just reads the voltage. So your code can only read one button at a time? Not that that would be an issue for most UI purposes

Any chance you can post the sketch?

Hi

I have no problem posting the code for anyone to use. Bare in mind it is a work in progress because the debouncing of the analog buttons still needs work.
I used an example I found on the dfrobot lcd shield which I am using and while it does work, it needs to be more efficient because it sometimes skips menus.

So my hardware is an Arduino uno, df robot lcd shield and a ds1307 rtc.
Many other peoples work.

The following site has wiring diagrams showing the hardware I am using

If you find anything that is not correct let me know. I am a beginner but starting to understand the Arduino a little now.
Code to follow

The #includes should be
LiquidCrystal.h
Wire.h
EEPROM.h
EEPROMVar.h
Unsure why they didn't show correctly. Possibly the brackets

Using my hardware this should just work but if you use a different shield then you need to find your own values using the following code
Put the end brackets back around LiquidCrystal.h before using. When you press a key the lcd screen will show you a value. Use this in the code.

Code:

#include LiquidCrystal.h
LiquidCrystal lcd(12, 13, 4, 5, 6, 7);
int a=0;
int bkl         = 6; 
        
byte bklIdle    = 10;       
byte bklOn      = 100;       
int bklDelay    = 10000;   
unsigned long bklTime = 0;


void setup()
{
  pinMode(bkl, OUTPUT);
  digitalWrite(bkl, HIGH);

lcd.begin(16, 2);

pinMode(A0, INPUT);

}
void loop()
{
a = analogRead(0);
lcd.clear();
lcd.setCursor(0,0);
lcd.print("  analogRead() ");
lcd.setCursor(0,1);
lcd.print("  value is :");
lcd.print(a);
delay(250);
}

Good job on the button code I've been trying to figure out the buttons on that shield for a few days now.

Thanks. Glad someone else can get some use out of it.
