Help toggling a relay via a TFT screen

Hi
I have a TFT screen which i have coded to help with testing trailer lighting while im working on the in my workshop (not possible to get a car to them all the time) so using a Mega and a 8-Way relay block i came up with this.
But having used it briefly, i decided that the "Side lights" needed to be toggled, so i can easily check the brake lights. idea being i can have the side lights turned on, and then press the button on TFT to put the Brake lights on for a set amount of time set in the "ON" delay setting.

I have tried i cane seem to work this out... code is below..

#include <TouchScreen.h>
#include <Adafruit_GFX.h>    // Core graphic library

const int relay1 = 53;       // output for relay - LEFT SIDE LIGHTS
const int relay2 = 51;       // output for relay - RIGHT SIDE LIGHT
const int relay3 = 49;       // output for relay - LEFT INDICATOR
const int relay4 = 47;       // output for relay - RIGHT INDICATOR
const int relay5 = 45;       // output for relay - BRAKE LIGHTS
const int relay6 = 43;       // output for relay - FOG LIGHT
const int relay7 = 41;       // output for relay - SPARE...
const int relay8 = 39;       // output for relay - SPARE...

That looks like a cut & paste error. You should be checking if the press is inside SIDEON_btn.

Wouldn't your code to turn on the side lights be almost identical to all the other buttons, just set the relay LOW to enable it? If you want them to toggle ON/OFF with each press, just introduce another variable to keep track of the current state and every time the SIDEON button is pressed, toggle it and set the relay

This:

#define SIDEON = true;

should be:

bool SIDEON = true;

perfect, well after a small tweak (again my mistakes..)

default should be false, otherwise it takes 2 presses to get it toggling properly on and off.
and the other being the "SIDEON" buttons was working, but i got a part of the line wrong for that button
SIDEON_btn.press(down && SIDE_btn.contains(pixel_x, pixel_y));
INSTEAD OF
SIDEON_btn.press(down && SIDEON_btn.contains(pixel_x, pixel_y));
BUT, its now working. THANK YOU!!

actually, regarding the screen, how do i get it to display and work upside down, so still portrait, but the other way.
i have changed the orientation but it didnt seem to change the touch screen values?

sorted, ran the touch calibration, with the screen orientation set to "2", and copied the results over. why didnt i try that before!
