I am new to coding but it is not working. The problem is described in the code comments. For my circuit i just combined these too screenshots and attempted to combine the code. One screenshot is the circuit for the motor the other is for the IR receiver. I have pretty much never coded c++ before so i mainly just got Arduino to work with the physical circuits. Please help.
Also, my computer is about to die so i will respond on my other account on my phone.

/*
My code is supposed to run a motor forward and backward, using the signals from an elegoo IR Remote and reciver module.
I am using a arduino mega. I also have a power module which is connected up to the bread board.
I am controling the motor with a L293D motor controller.
The ports things are hooked up to are as follow,
Motor controler
Enable- pin 5
DIRB- pin 4
DIRA- pin 3
IR reciver
G- ground (of power module)
R- vcc (of power module)
Y- pin 11
The code is supposed to make it so that when you push:
volume-up it spins forward;
pause it stops
volume-down it spins reverse
The problem
Whenever i press any button on the remote it imediatly starts moving the motor forward.
I only coded C++ a few times before, so most of this code is pulled together from 2 tutorials and the internet.
I have tried coding solutions but with my limited knowlage, it breaks the code and will not compile.
