Hello,
I'm trying to make a led switch for an aquarium. I'm using an arduino UNO and MCU friend 2.4" TFT Touch screen. The touch screen use ST7783 and i'm using for my project the following library :
-Adafruit_GFX
-UTFTGLUE
-SPI
-MCUFRIEND_kbv
-RTClib
-Wire
It's not my first project but i used to use URTouch library wich is unfortunately not working with my screen. Furthermore, it's my first project with a touch screen.
My goal is to drive a MOFSET with my arduino to switch on and off LED lights on my aquarium. MOFSET is to make it like sunset and moonset.
I'm having trouble with the touch part. I use it to program the rise up hour and the differents paramterers. I would like to detect if i touch this area to change the parameters.
A second little problem is that i'm not able to whrite hour with 2 digits .... If Someone can help me it would be nice. Here is my actual code inspired by exemples on MCUFRIEND Library :
#include <Adafruit_GFX.h>
#include <UTFTGLUE.h>
#include <SPI.h>
#include <MCUFRIEND_kbv.h>
#include <RTClib.h>
#include <Wire.h>
#include <avr/pgmspace.h>

RTC_DS1307 rtc;
#include <TouchScreen.h>

rtc.begin();
rtc.adjust(DateTime(F(__DATE__), F(__TIME__)));
}
void loop() {
while (true) {}
}
If the number is less than 10, print a 0 first.
i can send it on arduino but if i click everyhere nothing happen. To try to understand a bit how touch screen works i have made a quick program but the results seems weird :
